When assembling code with the Macro-Assembler in OS/2, there are
certain files and libraries that need to be included, so that the code
can be run under OS/2. These include the DOSCALLS.LIB library and the
OS2.INC include file. Dosexit is called as opposed to the traditional
int 21h that is used in DOS.
The following is a template of the basics needed to have workable code
under OS/2:
------------------------------------
includelib doscalls.lib
include os2.inc
dosseg
.MODEL [small,medium,large,etc.]
extrn dosexit:far
{BODY OF SOURCE CODE}
call dosexit
------------------------------------
A "SYS1107: The system cannot complete the process" will occur if a
MASM executable is run without the above include libraries and files.
A "SYS0491: The specified parameter for the session type is not
correct" error will be generated if a MASM executable file, without
the above include libraries and files, is brought into CodeView. The
dosexit replaces the standard DOS int 21h exit that is normal for DOS
MASM executables. The DOSCALLS.LIB and OS2.INC include files are
located on the MS OS/2 TOOLS disk that comes with MASM 5.10.
