The Main Storage Processor for the real S/36 (and also the S/34) could only
handle zoned decimal numbers.  The only instructions for handling these
numbers were add and subtract, with no decimal places.  There was only a
"factor 2" and result field.  "Factor 2" could only be up to 16 digits.  The
result field had to be at least the length of "factor 2" and could be up to
15 digits longer.  The compiler had to generate multiple instructions to
handle anything more complex than this.

The compiler put routines into the programs to use byte handling
capabilities for packing and unpacking numeric fields if needed.
