Does anyone have information  on how to interface IBM Dos pascal to
IBM macro assembler code?  More specifically what I need to know is
which registers I should save or initalize once I am in the assembly
routine. I have gotten as far as entering the assembly routine and getting it
to execute properly, however the program gets hung up when I "ret" to the
pascal main program.  Any info anyone can offer will be greatly appreciated,
Thanks in advance, 
              DC
