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

- Microsoft FORTRAN compiler for OS/2, versions 5.0, 5.1 
-------------------------------------------------------------------------------

SYMPTOMS
========

Linking with GRAPHICS.LIB in OS/2 may give the following error message:

  d:\lib\GRAPHICS.LIB(..\gr\qeswap.asm) : error L2029 :
  '___aDBswpchk' : unresolved external

CAUSE
=====

This is because GRAPHICS.LIB is designed for MS-DOS and is being linked with a
protected-mode FORTRAN library, which does not include the external references
required by GRAPHICS.LIB.

RESOLUTION
==========

Link with the real-mode library to correct the problem.

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

error if linked under OS/2:

  MAGNIFY.FOR
  COLOR.FOR
