I pulled this tidbit off the net a while ago; is this what you're trying
to do?

Software developers, you can use this little hack I just put together:
skipblock is a procedure which skips a %%BeginProcSet .. %%EndProcSet
region so that the interpreter won't scan the skipped text.

The only problem is how to get big companies to use this procedure...

--------------------------------
%!

%%BeginProcSet: skipblock 1.0 0
/stoppedreadline {
  /savedhandler errordict /rangecheck get def
  errordict /rangecheck { pop stop } put
  { readline } stopped
  errordict /rangecheck /savedhandler load put
  { exch pop true dup }
  { false }
  ifelse
} bind def

/readlinehead {
  /-str- exch def
  /-file- exch def
  -file- -str- stoppedreadline
  {
    {
      -file- (..............) stoppedreadline not
      { pop pop exit} if
      pop pop
    } loop
  } if
} bind def

/skipblock {
  /-save- save def
  /str 600 string def
  /str2 600 string def
  currentfile str readlinehead not { stop } if
  (%%BeginProcSet:) anchorsearch
  { pop /-name- exch def } { stop } ifelse
  {
    currentfile str2 readlinehead not { stop } if
    (%%EndProcSet:) anchorsearch
    { pop -name- eq { exit } if } { pop } ifelse
  } loop
  -save- restore
} bind def
%%EndProcSet: skipblock 1.0 0

%example

skipblock
%%BeginProcSet: foobar
(This stuff should be skipped) ==
(This stuff should be skipped) ==
(This stuff should be skipped) ==
(This stuff should be skipped) ==
%%EndProcSet: foobar
(This stuff should not be skipped) ==
