Responses to PostScript's ability to read input files has been yes it can,
but do it this way instead.  I am more interested in the answer to the
original question.  Can PostScript read input files.  True, PostScript is
a fully functional language with operators "file", "closefile", "read",
"write", "flush" and so on to work on general files; however, it appears to
me that all implementations of the PostScript language are severely limited
in their ability to use these capabilities which seem to restricted to
applying these operations to a single input stream and a single output
stream.  Admittingly, my experience is limited to desktop 300 dpi laser
printers.  There may be some high-end printers with built-in mass storage
that allow some useful application of these operators.  I would like to
know if there is any way to use them on a standard (low-end) serial
desktop PostScript printer (i.e. LaserWriter)
