The information in this article applies to:

Microsoft FORTRAN for MS-DOS and OS/2, versions 5.0, 5.1

SYMPTOMS

An attempt to compile an application in the OS/2 operating system fails and the compiler generates a protection violation. An attempt to compile the application in the MS-DOS operating system fails and the second pass of the compiler generates the following message:

   error F2128: ~k.~~~ : huge array cannot be aligned to segment boundary

The "~" and "~~~" characters represent symbol characters high in the ASCII table.

CAUSE

The application contains a complicated combination of DATA statements, EQUIVALENCE statements, I/O statements, or array declarations.

RESOLUTION

Many minor code changes eliminate this error. In the code example, reducing the size of the I array below 131,072 bytes or removing the DATA statement, EQUIVALENCE statement, or an executable statement eliminates the error.

STATUS

Microsoft has confirmed this to be a problem in FORTRAN versions 5.0 and 5.1 for MS-DOS and OS/2. This problem was corrected in FORTRAN PowerStation, version 1.0.
