Microsoft DOS Fortran 5.1 graphics - test-drb@ccmp.vtda.org

30 Aug 2018

...
  I am looking for a sort of 'hello world'
example and/or samples to use the
 graphics library in this compiler, some sample code.  My target is DOS and
 the Compaq luggable mono display.

 It looks like its all there, the library and include files for display adapters
and
...
  modes, but I cant find an example on the netwebs to
get me started.

 Anybody have a set of demo files or application source to study and  to use
...
  this?

 I have TurboC running on this machine, and the graphics are great.  Did
 Microsoft have a similar set of examples for Fortran?

  Randy,

this compiler can generate executables for DOS, Windows and OS/2.
It also came with the QuickWin libraries to create FORTRAN programs which
output text and graphics in Windows.
I am not 100% sure, but it is possible that the first release did not have
the QuickWin libraries and it came with an update.

When you install Microsoft FORTRAN 5.1 you have the option to install the
SAMPLES.

The README says:

\SOURCE\SAMPLES

  This directory also contains the source code for the graphics programs
  from chapters 11, 12, and 13 of the Microsoft FORTRAN Advanced Topics
  manual. Note that these examples require the graphics include files 
  FGRAPH.FI and FGRAPH.FD. These files are copied to an INCLUDE directory 
  by the SETUP program. In real mode (DOS), the programs must be linked with
  the graphics library GRAPHICS.LIB. In protected mode (OS/2), graphics is
  not supported, but you can compile text-only programs by linking
  with the text library GRTEXTP.LIB. The appropriate libraries are
  copied to your disk by the SETUP program. For example, use the
  following command line for DOS:

    FL COLTEXT.FOR GRAPHICS.LIB

  Or use the following command line for OS/2:

    FL COLTEXT.FOR GRTEXTP.LIB

  The programs are listed below:

Those examples cover many aspects of the system. I only used the Windows
part and I believe that under OS/2 there is no graphics, only cursor
addressing.
The graphics system offers similar capabilities to e.g. Borland's or Quick
C's capabilities.
