FIX: F1001 in codegen.c with IMPLICIT COMPLEX

The information in this article applies to:

• Microsoft FORTRAN PowerStation for MS-DOS, version 1.0

SYMPTOMS

Compiling a FORTRAN PowerStation routine that uses IMPLICIT COMPLEX may produce the following error:

   fatal error F1001: INTERNAL COMPILER ERROR
   (compiler file '@(#)codegen.c:1.167', line 309)
   Contact Microsoft Product Support Services

RESOLUTION

Explicitly declare all COMPLEX variables.

STATUS

Microsoft has confirmed this to be a problem in FORTRAN PowerStation version 1.0 for MS-DOS. This problem has been resolved with FORTRAN PowerStation maintenance release version 1.0a for MS-DOS.

FORTRAN PowerStation version 1.0 can be differentiated from the maintenance release version 1.0a by invoking the linker. Typing "link32 | more" from \F32\BIN directory will show version 2.8 for FORTRAN PowerStation version 1.0, and it will show version 1.0f for the maintenance release version 1.0a.

MORE INFORMATION

To demonstrate the problem, compile the sample code below with the FORTRAN PowerStation:

Sample Code

c--- compile options needed: none

      implicit complex (a-p,r-z)
      end
