Correction to my previous post:

After talking to our language guru, it is apparent that the // operator
acts in the following manner: outside brackets, it acts like a load exec,
the operator is looked up and then immediately executed, inside brackets
it acts like a load.

E.g.	1 2 //add
	stack contains: 3

E.g.	/d { 1 2 //add } def
	d load
	stack contains: { 1 2 --add-- }

The // operator should be conditionally used, interpreters prior
to version 25.0 do not support this operator.

The current version of the QMS-PS410 Adobe PostScript interpreter (52.4) 
does contain a bug which causes // to be interpreted improperly outside 
of brackets. This bug is fixed in the version of the PS 410 firmware which
is completing testing and will begin shipping soon.

For more information on when the new version will be available, please contact
QMS technical support at (205) 633-4500.

Thanks, Carl
