FIX: F2836 on Type Declaration After Entry Statement

The information in this article applies to:

• Microsoft FORTRAN PowerStation for MS-DOS, version 1.0

SYMPTOMS

Declaring a variable after an ENTRY statement may cause the compiler to generate the following error message:

   error F2836: statement out of order

RESOLUTION

Make all the type declarations before all the ENTRY statements to avoid this error message.

STATUS

Microsoft has confirmed this to be a problem in FORTRAN PowerStation for MS-DOS, version 1.0. 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 1.0f for the maintenance release version 1.0a.

MORE INFORMATION

Compiling the following code demonstrates the problem:

Sample Code

C No options required

      subroutine sub(x)
      entry suben(x)
      real x
      end

This error message can be avoided by moving the declaration for x above the ENTRY statement but below the subroutine statement.
