FIX: R6000 During Compile with F1L.EXE, Large DATA

The information in this article applies to:

• Microsoft FORTRAN for MS-DOS, version 5.1
• Microsoft FORTRAN for OS/2, version 5.1

SYMPTOMS

When compiling a program containing a large DATA statement with Microsoft FORTRAN version 5.1 under MS-DOS, the high capacity compiler may generate the following error:

   run-time error R6000
   - stack overflow

RESOLUTION

The error "F1901: Program too Large for Memory" is generated on this code if the high capacity compiler is not used. Reducing the size of the DATA statement within the program eliminates this problem.

STATUS

Microsoft has confirmed this to be a problem in Microsoft FORTRAN version 5.1 for MS-DOS and OS/2. This problem was corrected in FORTRAN PowerStation, version 1.0.

MORE INFORMATION

The following code reproduces the problem:

Sample code

      DIMENSION    F55LV(25,13)

      DATA ( ( F55LV(I,J), J = 1, 13 ), I = 1, 25 ) /
