DOCUMENT:Q111091 24-MAR-2000 [fortran] TITLE :FIX: Compiler Displays Incorrect Line-Number Information 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 - Microsoft Fortran Powerstation 32 for Windows NT, version 1.0 ------------------------------------------------------------------------------- SYMPTOMS ======== An attempt to compile a file that contains more than 32767 source lines may produce incorrect line-number information for compile-time error and warning messages appearing after the 32767th line in a file. The line numbers displayed are either negative or fall in the 0 (zero) to 32767 range. When compiling from within the Visual Workbench, you cannot automatically jump to lines containing these invalid line numbers. CAUSE ===== The line-number information is displayed as an INTEGER*2 value. RESOLUTION ========== If a subprogram is less than 32K in size, place the subprogram in a separate file when compiling. Once debugged, the source file can be added to the end of the original file if desired. STATUS ====== Microsoft has confirmed this to be a problem in FORTRAN PowerStation 32 for Windows NT and MS-DOS, version 1.0 and 1.0A. This problem was fixed in FORTRAN PowerStation, version 4.0. MORE INFORMATION ================ The following code can be compiled and run to create a sample that demonstrates the problem: Sample Code ----------- c Compile options needed: none c open(1,file='b.for',status='new') ! Creates B.FOR write(1,*) ' x = 0' do i=1,32*1024 - 1 write(1,*) ' x = x + 1' end do write(1,*) ' x == x + 1' write(1,*) ' print*, x' write(1,*) ' end' end Additional query words: buglist1.00 1.00A ====================================================================== Keywords : Technology : kbAudDeveloper kbFortranSearch kbZNotKeyword2 kbZNotKeyword3 kbFORTRANPower32100NT kbFORTRANPower100DOS kbFORTRANPower100aDOS Version : :1.0,1.0a Issue type : kbbug Solution Type : kbfix ============================================================================= THE INFORMATION PROVIDED IN THE MICROSOFT KNOWLEDGE BASE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.
