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
For example, the following sample programs included with FORTRAN produce this error if linked under OS/2:

MAGNIFY.FOR

COLOR.FOR

TEXT.FOR

ANIMATE.FOR

EGA.FOR
