DOCUMENT:Q118339 02-NOV-1999 [fortran] TITLE :PRB: DX1020 on a Call to OUTGTEXT under MS-DOS PRODUCT :Microsoft Fortran Compiler PROD/VER::1.0,1.0a OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- 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 Additional query words: 1.00 nofpsnt 1.00a ====================================================================== Keywords : Technology : kbAudDeveloper kbFortranSearch kbZNotKeyword3 kbFORTRANPower100DOS kbFORTRANPower100aDOS Version : :1.0,1.0a ============================================================================= THE INFORMATION PROVIDED IN THE MICROSOFT KNOWLEDGE BASE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.
