PS to my earlier posting:

This is how you can tell if your PostScript interpreter has // feature:

%%BeginProcSet: immediate-test 1.0 0
/has-immediate
(//add) token	% If immediately evaluated names are not implemented
		% this parses as / and /add
{ exch pop / eq not }
{ false } ifelse  % token should always succeed
def
%%EndProcSet: immediate-test 1.0 0
