That's because IBM never had one (they licensed one from MS,  and are
trying to break free from MS completely -- hence the new linker in Cset
3.0).

IBM will ship you an assembler if you buy the DDK cdrom.

The did (IBM MASM/2,  really just MS MASM),  but I'm not sure if they still
do.   IBM itself uses MASM 5/6 for 32bit OS/2 developemt (and this is what
you will get on the DDK).

It resolves dll references for many of the Dos...() calls.  It is included
for compatibility with OS/2 1.0.  Most compilers come with a lib (OS2.LIB,
OS2286.LIB, OS2386.LIB) that is a a superset of DOSCALLS.LIB.


 PE> OS2286.LIB       449536 bytes

This file contains all of the 32bit functions too (so that 16bit programs
can call them,  although I know of no compiler that supports this).  For
example,   Dos32Open().

 PE> With BCOS2 1.5 there is:

 PE> OS2.LIB          193606 bytes

I believe Borland has packed this with a smaller page size.

Instead of comaring file sizes,  use the MS/IBM lib.exe command to get a
listing of what is inside and compare that.  For example:

    LIB OS2.LIB, os2.doc
