BUG: Incorrect F2370 or C1900 when Compiling with /4Y

• Microsoft FORTRAN PowerStation for MS-DOS, versions 1.0 and 1.0a
• Microsoft FORTRAN PowerStation 32 for Windows NT, version 1.0

SYMPTOMS

When you compile a program using /4Yv that has errors in a declaration, one of the following error messages may be displayed:

• an infinite number of error F2370: "length specification illegal"

  -or-

• fatal error C1900: "Il mismatch between 'P1' version '0' and 'P2' version '19930414'"

RESOLUTION

Compile the code without using /4Yv to get a list of error messages. Correct the errors in the declaration(s). (The corrected code may be compiled using /4Yv.)

STATUS

Microsoft has confirmed this to be a bug in the FORTRAN PowerStation for MS- DOS, versions 1.0 and 1.0a, and the Microsoft FORTRAN PowerStation 32 for Windows NT, version 1.0. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

To demonstrate the problem, compile the sample code using the option /4Yv. The following error message will be displayed in a continuous loop:

   error F2370: length specification illegal

   error F2362: integer constant expression expected
   error F2830: END missing
