Q118339: PRB: DX1020 on a Call to OUTGTEXT under MS-DOS

Article: Q118339
Product(s): Microsoft Fortran Compiler
Version(s): 1.0,1.0a
Operating System(s): 
Keyword(s): 
Last Modified: 02-NOV-1999

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft FORTRAN PowerStation for MS-DOS, versions 1.0, 1.0a 
-------------------------------------------------------------------------------

SYMPTOMS
========

A program running under MS-DOS (not an MS-DOS prompt in Windows) calls OUTGTEXT,
and the following error message is generated:

  DOSXMSF : fatal error DX1020: unhandled exception: Page fault

CAUSE
=====

This error occurs if you have not successfully registered a font.

RESOLUTION
==========

Check the return status of REGISTERFONTS and SETFONT. If they return -1, then do
not call OUTGTEXT.

MORE INFORMATION
================

To generate the problem, compile and run the sample code below from MS-DOS (not
from an MS-DOS prompt in Windows).

OUTGTEXT still fails if the two lines are uncommented and the directory used in
REGISTERFONTS contains no .FON files or does not exist. The program runs
correctly if the two lines are uncommented and the directory used in
REGISTERFONTS does contain .FON files.

Sample Code
-----------

  c compile options needed: none

        INCLUDE 'FGRAPH.FI'
        INCLUDE 'FLIB.FI'
        INCLUDE 'FLIB.FD'
        INCLUDE 'FGRAPH.FD'
        write(*,*) setvideomode($MAXRESMODE)
  c      write(*,*) registerfonts("c:\f32\lib\*.fon")
  c      write(*,*) setfont("n1")
        CALL outgtext("abcde")
        read *
        END
