yes, you could forall the array of strings and get a sum of their lengths.
then allocate the string. then do a forall again on the array adding

that in ps is a bit beyond my abilities.

yeah. not really a call for env vars in an embedded app (ie a printer).
see Language.htm in the ghostscript doc dir (assuming a redhat install).
