Hi Mike--

    IBM still offers THK2ASM.  According to the printed Table of
Contents that came with DevCon 9, it's on Disc 1 in the Development
Tools (DEVTOOLS) directory, and the one-line description says: "Compiler
for OS/2 Warp Thunk Interpreter" - whatever that means.  I've not looked
at it, because I've never gotten around to learning 32-bit assembly
language.

    Besides, PL/I for OS/2 provides automatic thunking when calling the
16-bit KBD/VIO API functions.  No programmer intervention required--not
even as little as is required by C.  No need to worry about how it does
it.  Do I dare suggest that Alan should drop Pascal and use a real
language ?

    Regards,
