 And no published instruction set either?


 Consider this (assembly source) structure... (I may have some mistakes
in it, as my manuals are hiding in a storage facility).

arg1 data 1
arg2 data 2
retval data 0
...

 bal,15 dostuff
 data arg1 ;arg1/arg2/retval are the addresses of the data
 data arg2
 data retval
...

dostuff lw,14 *15  ;* is indirect access operator
  stw,14 param1 ;retrieve and save address of param1
  adi,15 1  ;increment link register
  lw,14 *15
  stw,14 param2
  adi,15 1
  ld,10 *param1  ;access param1 data
  mw,10 *param2
  stw,10 *15   ;save result return value
  adi,15 1
  b  *15   ;return from routine
param1 data 0
param2 data 0
