Well, whatever.  But there is a limit on Perl CGI's of about 40k.  And its
only because the code is stored in a TEXT resource.  So, either we live it
and work around it by storing most of the code in a text file and requiring
it in, OR we ask Matthias (sp?) to fix it.  And I don't really think he can
(I read - and hacked - the PCGI glue at one point in time.  In fact, my
changes are still shipping I believe.  But he reads the TEXT resource in
one chunk, and there is that 40k or something limit.)

The best thing to do is to move out to a text file and have the PCGI glue
basically just parse it apart and then run a script.  For example, what I
do is make a PCGI that contains code to read in stuff (basically the
cgi-lib.pl file is in the PCGI app.).  Then I just enter place (instead of
"real work for it to do) commands like so:

require "$in{'FILE'}";
&Main;

So that my entire program is read in from a text file and then it starts at
the subroutine called Main.  Thus I only have to have 1 PCGI running at any
time on the server.  And I don't have a limit on the code size.  And the
"shared" code of the cgi-lib is shared across all those scripts.  Think of
the space/time/ram savings here....

That's your best bet.
