OK. This clarifies what you meant. My use of MacPerl/CGI is usually 
_not_ for public web sites, so overlapping calls to MacPerl are rare. 
I'll watch more closely next time I do some process that takes a long 
time. I do get crashes occasionally with MaPerl/CGI, but I hadn't 
noticed a clear pattern.

And of course I agree with your suggestion for using a single CGI 
made versatile by having many subroutines or calls to other modules. 
This works well with my usual approach to developing CGIs, which I 
develop on Mac but mostly end up delivering to *nix or NT.

When I first set up a site for a client (or provide them the setup 
package, if that's their security condition), the first thing 
installed is a package of standard scripts, organized as subroutines 
in a single script/module. These do things like read out info about 
the OS, web server, Perl version, CGI.pm version, etc., and test user 
input and file access.

If these scripts work, then custom code can be built on a familiar 
base. In this approach, sometimes it's easiest to just drop the 
custom code into the standard 'package' (script/module) as added 
subroutines. If so, then consistently with your suggestion, what I 
develop on Mac as a single multi-function MacPerl script can go 
directly to its new home/platform with no change.

Anyway, KUTGW on your article. I'll read over your latest draft again 
in a few days.
