Q106728: BUG: DX1010 Running PowerStation Application from NMAKE

Article: Q106728
Product(s): Microsoft Fortran Compiler

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft FORTRAN PowerStation for MS-DOS, versions 1.0, 1.0a 
-------------------------------------------------------------------------------

SYMPTOMS
========

When using an MS-DOS extended version of NMAKE, the DOSXNT error

  DOSXNT : fatal error DX1010: DOS-Extended applications nested too deeply

occurs when attempting to run an application built with FORTRAN PowerStation from
the makefile.

CAUSE
=====

FORTRAN PowerStation for MS-DOS comes with two MS-DOS extenders:

DOSXMSF.EXE -- This is the MS-DOS extender used by programs created with the
FORTRAN PowerStation.

DOSXNT.EXE -- This is the MS-DOS extender loaded by PowerStation utilities such
as NMAKE and FL32.

The DX1010 error occurs when attempting to load one MS-DOS extender while the
other MS-DOS extender is in memory. These two MS-DOS extenders are not
compatible (see the Microsoft Knowledge Base article Q106567 for more
information on the incompatibility between DOSXNT.EXE and DOSXMSF.EXE).

RESOLUTION
==========

There are two alternatives to avoid the conflict:

- Do not use a version of NMAKE that loads DOSXNT.EXE.

- Compile the programs that are run from the makefile with FORTRAN version 5.1
  or earlier.

STATUS
======

Microsoft has confirmed this to be a problem in FORTRAN PowerStation version 1.0
and 1.0a for MS-DOS.

This is not a problem in FORTRAN PowerStation 32.

MORE INFORMATION
================

Running NMAKE that ships with the FORTRAN PowerStation on the sample makefile
below generates the DX1010 error when attempting to run HELLO.EXE:

Sample Makefile
---------------

  run: hello.exe
     hello
  hello.exe:
     fl32 <<hello.for
         print *, 'Hello'
         end
  <<KEEP
