When creating contained program-ids, I simply couldn't figure out how to stop the
middle end from the name of the contained program through the name mangler twice.

So, instead of using an uppercase 'X' as the substitute for a hyphen, I switched
to a '$', which is not part of the allowed COBOL character set for identifier
names.
