  • Microsoft Fortran PowerStation 1.0a for MS-DOS
  • Microsoft FORTRAN PowerStation 32

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
