Quick Start: TextWare Lite for DOS
Welcome to TextWare Lite for DOS 4.1
TextWare Lite is a full-text retrieval program. We hope the product
works well for you. We believe we have succeeded in making this
product intuitive and easy to use.
Getting Help
For instant help while using the program, be sure to use the F1 Help
key for context-sensitive help; access the on-line User Manual for
more details.
What Kind of User Are You?
Are you a manual reader, a manual skimmer, or someone who consults
a manual only as a last resort? Are you a novice computer user?
An experienced DOS user? A current TextWare 3.0 user?
We have tried to design this document with all these types of users
in mind.
If you are a TextWare 3.0 user, you should get enough information to
get started by following these abbreviated instructions.
If you are an experienced user (or simply intrepid), the same route
may also work for you, at least for getting started.
If you are a novice, we recommend that you skim Quick Start to get an
overview of how to use the program. Then, for more specific information,
see Chapter 2 - TextWare Lite For DOS Tutorial, in User Manual in the
Help Menu. If even more in-depth information is needed, access the
complete user's manual (TWLITDOS.TWC) in the TWLITE subdirectory (by
closing this CardFile by typing ALT-F, then C to Close, to OK
closing the highlighted entry, for Open, ALT-P to select a new
path, typing \TWLITE , highlighting TextWare Lite For DOS User
Manual, and pressing ).
Hardware Requirements
Make sure that you have at least 1.5 Mb of disk space available and
that your computer has a minimum of 640 kb of RAM. In many instances,
TextWare Lite will recognize and use up to 32 Mb of expanded or extended
RAM installed in your computer. See Memory Usage in the Reference
Section for more information.
Mouse Setup
TextWare Lite supports a mouse. If you have a mouse, install it in
accordance with the mouse manufacturer's instructions. Load the
mouse driver before starting TextWare.
Using TextWare Lite for DOS
The menus in TextWare Lite work much like those in Windows and other
graphical interfaces. Because it is a character-based DOS application,
however, the menu screens (and mouse cursor) are all drawn using ASCII
characters.
Searching a CardFile
To search through the selected CardFile, press the Space Bar or
select Enter from the Search menu. The Search window displays.
Notice that all the unique words in the CardFile are listed in the
Word Wheel.
You may now select one or more words from the Word Wheel. Use the up
and down arrow keys and press F5, or type the words and search for
them. You may use any of the Boolean operators (OR, AND, etc.) as
search conditions. A space between words is equivalent to AND.
Choose OK (you may simply press Enter while the brackets around "OK"
are highlighted) to execute the search.
Upon executing the search, the program displays a Hit List, or list
of all the Cards where the specified words occur. The Cards are
listed by their Short Displays, a one-line description.
Select one of the hits in the list (highlight the Short Display and
press Enter or double-click with the mouse) to display the text in
the Card.
When the text is displayed, the F2 key jumps to the next match within
a single Card, while the + key moves to the next hit Card (use
Shift+F2 and - to go backwards). The F10 key displays the Hit List
again.
You may also choose to perform a phrase search (exact order of words)
or a proximity search (words found in the same sentence or
paragraph).
Links
Words displayed in a light-blue color (reverse video for monochrome
monitors) are Hypertext Links. Links can be associated with another
word or phrase, an image, a Sticky Note, or even an external program.
Position the cursor and press Enter on a Link (or double-click with
the mouse) to access the word, image, or program to which it is
linked. The bottom help line displays the Link type when the cursor
is on the Link.

PROJECT OVERVIEW
Conversion of the information from the original folio to a computerized
digital format was undertaken to facilitate the presentation and analysis of
earth-science data. Digital maps can be displayed at any scale or
projection, whereas a paper map has a fixed scale and projection. However,
most of the maps on this disc are not intended to be used at any scale more
detailed than 1:500,000.
A geographic information system (GIS) allows combining and overlaying of
layers for analysis of spatial relations not readily apparent in the
standard paper publication. Digital information on geology, geophysics, and
geochemistry can be combined to create useful derivative products.
HISTORY OF THE MAPS
In 1986 and 1987, the U.S. Geological Survey (USGS), the Dirección
General de Geología, Minas e Hidrocarburos, and the Universidad de Costa
Rica conducted a mineral-resource assessment of the Republic of Costa Rica.
The results were published as a large 80- by 50-cm color folio (U.S.
Geological Survey and others, 1987). The 75-page document consists of maps
as well as descriptive and interpretive text in English and Spanish covering
physiographic, geologic, geochemical, geophysical, and mineral site themes
as well as a mineral-resource assessment. The following maps are present in
the original folio:
1) Physiographic base map at a scale of 1:500,000 with hypsography,
place names, and drainage.
2) Geologic map at a scale of 1:500,000.
3) Regional geophysical maps, including gravity, aeromagnetic, and
seismicity maps at various scales.
4) Mineral sites map at a scale of 1:500,000 showing mines, prospects,
and occurrences.
5) Volcanological framework of the Tilarán region important for
epithermal gold deposits at a scale of 1:100,000.
6) Rock sample locations, mining areas, and vein locations for several
parts of the country.
7) Permissive areas delineated for selected mineral deposit types.
8) Digital elevation model.
This CD-ROM contains most of the above maps; it lacks items 1 and 8 and
the seismicity and aeromagnetic maps of item 3. The linework was digitized
from preliminary and printed maps with GSMAP (Selner and Taylor, 1987), a
USGS-authored program for map editing and publishing. Conversion from GSMAP
to ARC/INFO was accomplished through the use of the GSMARC program (Green
and Selner, 1988). The arcs and polygons were tagged using Alacarte
(Wentworth and Fitzgibbon, 1991).

MAP PROJECTION
The map projection is not described in the original publication.
However, the reference on the base map refers to U.S Defense Mapping Agency
(DMA) Tactical Pilotage Charts for which the projection is Lambert conformal
conic with the following parameters:
Sphere Clarke 1866 spheroid
1st standard parallel 9 20 0.000
2nd standard parallel 14 40 0.000
central meridian -85 0 0.000
latitude of projection's origin 0 0 0.000
false easting (meters) 0.00000
false northing (meters) 0.00000
CAUTIONS RELATING TO USE OF THE MAPS
One of the advantages of digital maps is the ability to change the map
scale. However, the users of this disc should respect the intentions of the
authors and recognize certain limitations of digital maps. The geology of
Costa Rica and most other layers are intended to be used at a scale of
1:500,000; they are not intended to be used at a more detailed scale. Costa
Rica is about 34 inches long on its longest NW-SE axis at the published
scale of the map. The Tilarán region layers are intended to be used at a
scale of 1:100,000 or smaller.
Furthermore, the geologic map is primarily a bedrock map, which depicts
geologic materials present beneath the soil or a relatively thin mantle of
surficial deposits, not necessarily the surficial material itself.
ONLINE ERRATA REPORTS
If bugs and errors are found in the CD-ROM after release, a notice will
be posted on the World Wide Web reached via the Internet. The bug report
can be viewed and retrieved with the freeware program Mosaic by linking to
the following address:
http://info.er.usgs.gov/reports/digital_data_series/
Mosaic for DOS, Macintosh, and UNIX is available via anonymous ftp at:
ftp.ncsa.uiuc.edu
The Costa Rica ARC/INFO Export files will also be available online at the
same address as the bug report shortly after the CD is published.
GRAPHICS FORMATS AVAILABLE
The following formats are available on the CD-ROM:
1) U.S. Geological Survey map display (GIV) software for DOS computers.
For DOS users, the CD-ROM contains MAPPER display software, a user-
friendly program that displays the interactive vector map, and VIEWLBL,
which displays the raster image of the geologic map and performs spatial
analysis. MAPPER and VIEWLBL are part of the Geologic Information
Visualization (GIV) software package by Russell A. Ambroziak. The raster
image is stored at 150-m resolution in the original Lambert conformal conic
projection. The DOS vector version is stored unprojected in decimal
degrees.
2) ARC/INFO Export format.
These coverages are used for spatial analysis, derivative products, and
to-scale plots on the Versatec electrostatic plotter. The format is
compatible with Environmental Systems Research Institute's ARC/INFO Version
6.1.2 or later. The files are simple text and should be transmitted in
ASCII mode.
3) ArcView format.
ArcView is an easy-to-use graphics display package by the authors of
ARC/INFO. It uses the same coverages and images as ARC/INFO. This CD-ROM
contains ArcView coverages for both UNIX and Microsoft Windows. It also
contains export files that can be copied to other Arc/View platforms and
imported to ArcView. The "view" file that stores the key to the maps was
developed under ArcView 1.
4) U.S. Geological Survey Digital Line Graph (DLG) Optional format (U.S.
Geological Survey, 1986, 1987, and 1989).
The DLG format is a U.S. Geological Survey standard for storing
topologically structured files. It results in a compact ASCII file that is
compatible with a variety of graphics software. Only the geology layer was
converted to this format. It excludes the annotation.
5) Drawing Exchange File (DXF) format.
DXF format is popular in computer-aided design (CAD) software. Only the
geology layer was converted to this format. The polygons are not color-
filled but are labeled with text rock unit codes.
ARC/INFO EXPORT FILES
The export files were created with the NONE compression option and
MAXLINES = 15000 option to maintain compatibility with PC/ARC. They should
be transmitted as ASCII text files. The 1040.GRA plot files are UNIX
binary. To import the coverages, create the workspaces, copy the files from
the CD-ROM and run the IMPORT.AML in each directory. As an example, the
commands for creating the workspaces in UNIX follow:
arc
cw domain
cw geochem
cw geol
cw gold
cw gravbo
cw gravis
cw mines
q
cp /pdd/dds19/datafile/export/domain/* domain/.

DLG FILES
The DLG format is a U.S. Geological Survey standard for storing
topologically structured files. It results in a compact ASCII file that is
compatible with a variety of graphics software. Only the geology layer was
converted to this format. It excludes the annotation.
The Costa Rican geologic map and legend have been converted to Digital
Line Graph (DLG) Optional format files. The DLG files contain tagged
polygons and arcs. Annotation labels are not supported in the DLG format.
The geology and legend are contained in the following files:
fline.cma fault line types
geol.dlg geology and faults in Lambert projection
geoldd.dlg geology and faults in decimal degrees
geoleg.dlg legend geology and faults in Lambert projection
geolegdd.dlg legend geology and faults in decimal degrees
gline.cma contact line types
ptype.cma rock unit codes, descriptions, colors for Versatec
plotter
scale.dlg scale bar in Lambert projection
scaledd.dlg scale bar in decimal degrees
Although the conversion to ARC/INFO is more easily accomplished with the
ARC/EXPORT files included elsewhere on this disc, the following instructions
for converting DLG files to ARC/INFO may be illustrative for converting DLG
files to non-ARC/INFO platforms. These methods for converting DLG files to
ARC/INFO coverages have been adapted from ARC/INFO manuals (Environmental
Systems Research Institute, 1990):
1) Copy the .dlg and .cma files from the CD-ROM. For instance, from a UNIX
prompt, type:
arc
cw costa.geol create arc/info workspace
q
cd costa.geol
cd info put the .cma files in the INFO
directory
cdrom in
cp /pdd/cdrom/datafiles/dlg/*.cma .
cd ..
cp /pdd/cdrom/software/dlg/*.dlg . put the .dlg files in the
workspace
cdrom out
2) Launch ARC/INFO and create a lookup table for the rock unit codes:

4) The dlgarc command creates .pcode and .acode INFO files which are used to
link the .lut tables to the coverage. Some of this linking may be automatic
in non-ARC/INFO conversions. If not, the technique is to use the common -id
field to join .pcode and .acode to the coverage, then use major1 and minor1
as the common fields to join ptype.lut, fline.lut, and gline.lut to the
coverage.
Choose a dlg file to convert - Lambert (geol.dlg) or Decimal Degrees
(geoldd.dlg). The following example is for the Lambert coverages:

DXF FILES
The geology, faults, and legend of the Costa Rica folio are stored in
Drawing Exchange File (DXF) format, which is a standard graphical file
format in computer-aided design (CAD) systems. The rock unit polygons have
rock unit label text but not color fill. The map units are in decimal
degrees. The geologic map is contained in the following files:
datafile directory containing data files
dxf directory containing DXF files
faults.dxf fault arcs
geol.dxf geology polygons, labels
geolanno.dxf rock unit annotation and leaders
geoleg.dxf legend polygons, labels, annotation, and lines

The arc colors listed above are inappropriate for a geologic map but are
unique and modifiable. Each type of arc is a separate layer. The polygon
labels and annotation text are also in separate layers.
CONVERSION TO ARC/INFO
Although the conversion from text files to ARC/INFO is more easily
accomplished with ARC/EXPORT files, which are included elsewhere on this
disc, the following instructions for converting DXF files to ARC/INFO may be

ARCVIEW 1
The CD-ROM includes coverages that can be displayed with ArcView 1
(Environmental Systems Research Institute, Inc., 1992). ArcView is an easy-
to-use graphics display package by the authors of ARC/INFO. ArcView
displays the same coverages and images as ARC/INFO. ArcView 1 is available
for both UNIX and Microsoft Windows computers. This CD-ROM contains ArcView
for Windows programs but not ArcView for UNIX programs. It does, however,
contain coverages and views for both types of computers.
See "Installing ArcView1 Program and Coverages for Windows" (the next
card)
for instructions on installing and launching ArcView 1.
INSTALLING ARCVIEW 1 PROGRAM AND COVERAGES FOR WINDOWS
This section contains instructions for installing and launching
ArcView 1 for Windows and launching instructions for ArcView 1 for UNIX.
Installation instructions for ArcView 1 for Microsoft Windows:
1) Please observe the following system requirements:
80386 or better CPU
Math coprocessor recommended
Windows 3.0 or higher
4 Mb of RAM, 8 strongly recommended
15 Mb of disk space
Super VGA graphics system, 256 colors, 640x480 pixels minimum, 1024x768
pixels strongly recommended
Microsoft compatible mouse
Windows-supported printer
2) Decide where you are going to put ArcView 1 on your hard drive. You must
have 15 Mb of hard disk space.
3) Launch Windows. Launch the File Manager. Use the File Manager to find
the CD-ROM drive and the \DDS19\ARCVIEW directory. Double-click on
ARCVIEW.EXE. This starts the self-installing procedure. At the licensing
agreement document select the File menu, Exit. ARCVIEW asks for a hard disk
drive letter designation and a directory name to store the program. The
default is \ARCVIEW1.
4) When the install finishes, ArcView will tell you to examine SETUP.TXT and
use it to modify AUTOEXEC.BAT and CONFIG.SYS. Exit from Windows and use the
following instructions modified from SETUP.TXT.
Add the following environment variables to the C:\AUTOEXEC.BAT file:
set AVHOME=c:\arcview1 (or wherever you decide to put it)
set PATH=%PATH%;%AVHOME%\bin (Add Arcview1's bin directory
to the path )
set HOME=c:\arcview1 (or wherever you decide to put it)
set TEMP=c:\temp (Make sure the directory
exists. A RAM disk works the
best, i.e, TEMP=d:\. This
variable should already be
present if Windows has been
installed.)
Add the following line to the C:\CONFIG.SYS file:
FILES=65
Rename the original lineset. Copy the custom lineset from the DDS-19 CD-
ROM.
CD C:\ARCVIEW1\SYMBOLS
REN AV.LIN AV_ORIG.LIN
COPY D:\DDS19\DATAFILE\AVPCCOV\AV.LIN
5) Launch Windows. Launch the File Manager again and copy the
DDS19\DATAFILE\AVPCCOV directory to your hard disk. This step is optional
but ArcView runs very slowly if the coverages are located on the CD-ROM.
Double-click on the ArcView icon. Navigate the drive and directory menus to
D:\DDS19\DATAFILE. Double-click on the COSTA.AV view. ArcView will
ask to search for the GEOL coverage. Select "Yes". Navigate to the AVPCCOV
folder and double-click on the GEOL file. The ArcView Teacher will
automatically find the full path to the rest of the coverages and launch the
view. Select the "File" menu, "Save As". Save the view so the next time
you launch it, the path will be remembered.
INSTALLING ARCVIEW 1 EXPORT FILES AND COVERAGES FOR UNIX
Insert the disc in the CD-ROM drive. Some UNIX computers require a
mount command such as "cdrom in cdrom". The ArcView coverages are available
in two formats - as raw coverages and as export files.
Importing raw UNIX coverages:
The raw coverages are in tar format. If the cdrom is directory /pdd, un-
tar with the command:
tar xvf /pdd/dds19/datafile/avuxcov.tar
Importing ArcView Export files:
The ArcView export files are in directory /dds19/datafile/avexport.
As an example, if the cdrom is directory /pdd, the commands for importing to
UNIX follow:
arc
cw avexport
q
cd avexport
cp /pdd/dds19/datafile/avexport/* .
arc
&r import
For both raw coverages and export files, copy the lineset AV.LIN to your
home directory, which is usually your login area.
Ask your system manager how to launch ArcView 1 on your system. It may
involve inserting the following commands in your .cshrc file:
# s1 sets up ArcView1, s2 sets up ArcView 2
# av1 launches ArcView 1, arcview launches ArcView 2
alias s1 'setenv AVHOME /esri60/arcview'
alias av1 '/esri60/arcview/bin/arcview'
alias s2 'setenv AVHOME /esri70/arcview'
Launch ArcView 1, select the "File" menu, "Open". Navigate the "Open"
dialog to the CD-ROM directory "cdrom/dds19/datafile/avuxcov". Double-click
on the "costa.av" view. ArcView asks if you want to search for the "geol"
coverage. Select "Yes". Double-click on the "geol" file. The ArcView
Teacher will automatically find the full path to the rest of the coverages
and launch the view. Select the "File" menu, "Save As". Save the view so
the next time you launch it, the path will be remembered.
USING ARCVIEW 1
The CD-ROM includes coverages that can be displayed with ArcView 1
(Environmental Systems Research Institute, Inc., 1992). ArcView is an easy-
to-use graphics display package by the authors of ARC/INFO. ArcView
displays the same coverages and images as ARC/INFO. ArcView 1 is available
for both UNIX and Microsoft Windows computers. This CD-ROM contains ArcView
for Windows programs but not ArcView for UNIX programs. It does, however,
contain coverages and views for both types of computers.
See "Installing ArcView" for instructions on installing and launching
ArcView 1. After ArcView is launched, the Table of Contents or map key
appears on the left and the map on the right. ArcView has a time-saving
feature called interruptible re-draw. This means that the tools, menu
items, and themes in the Table of Contents are selectable even while ArcView
is re-drawing the map. A mouse-click or mouse-drag will interrupt the
drawing and take effect within a few seconds. There is no need to wait for
complicated maps to finish drawing if you already know what you want to do
next.
The initial width of the Table of Contents is too narrow to see all the
text in the key. The width can be increased by dragging on the edge of the
table with the mouse. Increasing the width of the Table of Contents causes
it to overlap the map, but the map can be brought to the foreground by
clicking on its title bar or edge.
The individual layers (data themes) in the Table of Contents are turned
on and off in the display by selecting the checkboxes along the left side of
the map key. Legends below individual themes can be turned on and off by
dragging on the triangle on the right side of the key. Colors of points,
lines, and polygon fill can be changed by double-clicking a theme, selecting
the legend checkbox in the Properties dialog, then double-clicking on the
color.
Zooming in and out are accomplished in many ways in ArcView. One way is
to single-click on the items in the Table of Contents so they appear
slightly raised. Single-click again to de-select them. Choose just the
items you want to zoom to, then select the "fit-selected-features-to-window"
icon, which is the second icon from the left in the map window. It looks
like a down arrow over a stack of paper. Select the "GRID" theme to zoom
out to the full extent of the view.
Another way to zoom in is with the "zoom-to-a-box" tool on the tool
palette. The tool palette can be brought to the foreground with the
"Windows" menu, "Tools..." item. Just select the dashed-line-box tool,
which is the second from the bottom on the left, then drag in a diagonal
movement across the area you wish to zoom to.
If you view the "Geology annotation" theme, be sure to turn on the
"Geology annotation leaders" as well. Otherwise some unit names appear to
float in the wrong unit.
The order of layers in the Table of Contents is critical. All layers are
opaque, and the color-fill polygons obscure everything beneath them. For
this reason, color-fill themes are positioned lowest on the key and
duplicated as non-filled versions higher up in the key. For instance,
"Geology, solid color fill" is low in the Table of Contents because it
obscures everything beneath it. There is also a non-filled version called
"Geology, outlines only" higher up in the key. Should it be necessary to
change the order of items in the Table of Contents, they can be dragged to a
new position with the mouse.
To create hard copy of the ArcView 1 graphics screen, select the camera
icon on the main display screen. This creates an encapsulated PostScript
(EPS) file of the display image, which can be printed with standard
commercial graphics software.

MAPPER.EXE: Displays vector-based map files (ASCII .MAP file). Creates
image .XMP files (if running in extended VGA; .VMP if running
in VGA etc.), MAPPER.MRK files, and ASCII .LAB files.
RASTMAP.EXE: Makes raster-based map files for printing and map keys and
for analysis of map data. Reads a .PMP (Paper MaP) file
describing the map and the lines, symbols and text to be
plotted on the map and creates, edits and prepares for
printing maps and keys.
RASTMAPA.EXE: Finds areas of polygons in raster-based images. Creates an
.ARE file.
RASTMAPE.EXE: Edits raster print image file.
RASTMAPF.EXE: Creates the final raster image print file.
RASTMAPK.EXE: Creates a key of the mapped units in the raster image print
file.
RASTMAPM.EXE: Makes a raster print image base file.
RASTMAPP.EXE: Makes an .PMP control file from the .MAP control file.
RASTMAPS.EXE: Determines the pixel size for the desired scale of the print
image.
RESET: Boots the Video Board and turns it off. Used if a program
accidently exits without returning to text mode.
VIEWLBL.EXE: A simple raster image display program. Information displayed
on the screen can be saved as .PCX (by pressing F4) or .GIF
(by pressing F5) files.
USING MAPPER
Typing RUNMAPR at the DOS prompt in the \GIV subdirectory will start the
MAPPER display software. If you see the error message, "Could not boot the
board," then, either the video card is configured for a setting other than
640 by 480 pixels by 256 colors, or your video card may not be supported by
the graphics subcode.
The first choice, DOM_NAME.XMP, appears on a separate screen. It is a pre-
drawn view of the DOMAIN.MAP map. It shows the tract names without clicking
on the polygons. To view it, press . To proceed to the other
interactive maps, press .
There are four other interactive maps:
DOMAIN.MAP Permissive tracts for mineral deposits in Costa Rica
GEOLOGY.MAP Geology, faults, mineral deposits of Costa Rica
GOLDAREA.MAP Geology of Tilarán gold-mining area
GRAV_BO.MAP Bouguer gravity map of Costa Rica
To draw a latitude and longitude grid, select the Draw menu, Graticule. To
display the map key, select the Analyze menu, Key menu, Large. To flash all
instances of a given unit on the map, Select the Color menu, Flash; then
click on a color in the key or the map.
DOMAIN.MAP and GRAV_BO.MAP
These files display permissive tracts and gravity contours for Costa Rica.
To display the geology arcs on top of these maps, select the Analyze menu,
Plot menu, Lines, geology.
GEOLOGY.MAP
This map shows the rock units and faults for the entire country. To display
the mineral deposit points, select the Analyze menu, Plot menu, Icon Loctn.
To display the deposit names, select Icon Names and click on any deposit
point. The name appears in the lower left corner of the screen.
GOLDAREA.MAP
This map initially draws the geology, faults, hydrothermal areas, and
mineral deposit points. To display the deposit names in the Tilarán gold-
mining area, select the Analyze menu, Plot menu, Icon Names, and click on
any deposit point. The deposit name appears in the lower left corner of the
screen.
The user can change the appearance of interactive maps by modifying the
'.MAP' file. See the section titled "Mapper User Manual" for details.
USING VIEWLBL
Typeing RUNVIEW at the DOS prompt in the \GIV subdirectory will start the
VIEWLBL display software, showing a list of '.LBL' files. Move the
highlight bar over 'GEOLOGY.LBL' with the mouse or cursor keys and press
on the keyboard, or press the left mouse button. This displays a
bitmap of the geologic map of Costa Rica. Menu items in VIEWLBL allow
zooming, panning, histograms, etc.
The .LBL file can be converted to a Targa file with LBL2TGA. The Targa file
is printable with standard commercial software. A pixel size of 84.6667 m
was chosen to create a 1:500,000 scale map of 40.32 by 30.24 inches if
printed at 150 dots per inch (dpi). The file size is 27 Mb. Users can
modify the '.PMP' file and re-run RASTMAP to change the size, color,
projection, etc, of the bitmap file to suit their needs. See the section
titled "Rastmap User Manual" for details.
