FIX: Error F1001 in range.c Compiling with -Ox

The information in this article applies to:

• Microsoft FORTRAN PowerStation 32 for Windows NT, version 1.0

SYMPTOMS

An attempt to compile a program, using the -Ox option, that contains an GOTO statement in combination with the INCLUDE may fail with the following error message:

   fatal error F1001: INTERNAL COMPILER ERROR
   (compiler file '@(#)range.c:1.0', line 2279)

CAUSE

The INCLUDE file contains an array on the left side of an assignment statement, and the array is not declared. Because undeclared arrays appear as functions to the compiler, the following error message should have been generated:

   error F2515: left side of assignment illegal

RESOLUTION

Make sure all arrays are properly declared.

STATUS

Microsoft has confirmed this to be a problem in Microsoft FORTRAN PowerStation 32 for Windows NT, version 1.0. This problem was corrected in Microsoft PowerStation 32, version 4.0.

MORE INFORMATION

The following program illustrates the problem:
