I am having difficulty getting the following code assembled

much better, but I have not been able to find a copy. Do
you know if TASM might be able to assemble the following

You can write inline assembler in your C source, but the Turbo 2.0x
compiler can't do the assembly by itself -- it uses Turbo Assembler
for that.
annoyingly, I think that version is too early to
support inline assembler,
which makes it less useful for any actual DOS development work :(
TurboC 2.0x DOES explicitly support inline assembler.
