OpenWatcom FORTRAN 77
(ver 1.90)
Commercial made Abandoned Freeware


Orignally a commercial product from Sybase, The Watcom (now OpenWatcom) 
FORTRAN 77 compatible compiler is now Open Source freeware.  The compiler 
needs to be setup from an installation file (file = f77_1-9.exe).

This compiler runs under native DOS, but can build code for native 
16 and 32 bit DOS, 16 and 32 bit Windows, OS/2, Linux, Netware, and RDOS.  

Autoexec.bat and Config.sys needs to be modified.  The setup program will 
make the modifications for you, or (preferrably) the installer can save
the changes to files named "autoexec.dos" and "config.dos".  Running the 
file "OWSETENV.BAT" will also set the Open Watcom Build Environment.  

Source code for the compiler can be found in the SRC directory.  Examples 
can be found in the SAMPLES directory.  Documentation in PDF format can 
be found in the DOCS directory.
