That's easy. Write it your way.

What's so hard? I picked 3 stubs pretty much at random and ran alp:

[j:\tmp\0]dir /kma:-d
7-31-03 8:53 2,321 0 aspisegs.asm
4-24-02 15:08 2,387 0 atapiseg.asm
8-11-96 22:43 1,063 0 devhdr.inc
9-21-01 9:39 1,594 0 ETHRSEGS.ASM

[j:\tmp\0]for %X in (*.asm) alp %X

With the results:

[j:\tmp\0]dir /kma:-d
7-31-03 8:53 2,321 0 aspisegs.asm
7-31-03 8:58 393 0 aspisegs.obj
4-24-02 15:08 2,387 0 atapiseg.asm
7-31-03 8:58 382 0 atapiseg.obj
8-11-96 22:43 1,063 0 devhdr.inc
9-21-01 9:39 1,594 0 ETHRSEGS.ASM
7-31-03 8:58 345 0 ETHRSEGS.obj

The discerning reader will notice that aspisegs.asm has today's date. I
did need to tweak aspisegs.asm, but that that's to be expected since the
vast majority of the drivers were built with MSC and MASM. Mastrianni's
book being of the same vintage will provide plenty of MSC/MASM examples.
It won't help you understand why IBM decided that alp did not need to be
backward compatible with masm. FWIW, I have been told that many of
Mastrianni's examples are broken and his driver style is poor. However, I
haven't looked a copy of this book since probably 1991 or so when we were
doing the requirements for a port to OS/2 1.3, so I'll leave it to the
philosophers to debate this.

Just to see if I could make the assembly process harder, I tried wasm,
with the results:

[j:\tmp\0]for %X in (*.asm) wasm %X

Guess not.
