MS-DOS with the exception of DSWIN which is an MS Windows program.
Left click on the file from your browser, your system should open a Save File window. Select a destination folder and click Save. In most cases the file will begin to download.
Sometimes instead of downloading, the 3 character extension of the file name (mime type) causes an application on your system to run, attempting to use the file as input. If this happens, instead of left clicking, try one of the following:
TIP: If you continue to have problems, clear your browser's disk cache and try again.
Look for a file with a name starting with 'readme' or ending with '.doc'
To be safe you should download all files. Some files may be required for the program to run. For example, vertcon.exe requires the 3 additional files vertcone.94, vertconw.94, and vertconc.94. Be sure to read the associated README file or program documentation before you download files.
These are compressed archival files, which when 'unzipped' will expand into all the files required for the program.
Run an unzip utility. If you do not have it, the pkzip shareware may be downloaded from www.pkware.com, or search for other unzip utilities at CNET's download.com
.exe = The program (This is the main file you need).
.bat = MS-DOS Batch Program file.
.txt = Documentation
.1st = Documentation
.doc = Documentation, usually ASCII, could be WordPerfect.
.asc = Documentation in ASCII format
.wp = Documentation in Word Perfect format
.hlp = Help File
.par = Parameter file, required for Nadcon, Geoid, Deflec
.dat = Data files, ASCII Format.
.las = Binary files required by program Nadcon
.los = Binary files required by program Nadcon
.geo = Binary files required by program Geoid
.eta = Binary files required by program Deflec
.xii = Binary files required by program Deflec
.94 = Binary files required by program Vertcon
.bas = Basic Program (May not work on your system).
.zip = Zip (Archived and compressed files).
.h = Source Code header files.
.c = Source Code written in C programming language
.cpp = Source Code written in C++ programming language
.for = Source Code written in FORTRAN Programming language
.f = Source Code written in FORTRAN Programming language
Download all source code (.c, .f, .for, .h) files to your SUN Unix system and recompile them there.
You must also convert the Nadcon MS-DOS binary grid files (.las, .los) to SUN binary grid files. Run program nadgrd.exe on the PC to convert the MS-DOS binary files to ASCII, move these ASCII files to your SUN system, then run nadgrd(recompiled) on your SUN system to convert the ASCII files to binary. See Nadcon's readme.txt for more details. Programs Geoid, Deflec, Vertcon, all have similar file conversion utilities.
