I have a UNIX Bourne shell script which you could probably mangle into DCL (if
that's what you need).  It intercepts each showpage command, does some scaling
and translating, and you end up with four-up output.  It doesn't ALWAYS work,
but I've never had any incentive to investigate it too far, since the original
solution was so simple.  Find attached to this message two scripts: PSx4, for
four-up output, and PSx2, for two-up.  Note that these script write to stdout.
They can read from stdin, or from files specified on the command line.
