in thread CGI Post query

You asked why place the form into a hash?
The Perl program uses 6 Perl Modules, collects information from about 60 fields and then makes calls to the other modules to enter and retrieve information from databases, check data constraints, etc. Presently the code calls one param at a time and then passes upto a dozen scalar variables to the various other procedures in different modules.
There are no checkboxes or radio buttons, and currently there are no plans for any files to be uploaded, and this probally won't change in the future.
It just seemed easier to load the form into a hash and then pass the reference of the hash around all the different modules to access all the various parts of the form, rather than have having vast amount of scalar variables declared all over the different modules .
But perhaps I'm wrong, it won't be the first time ;-)
Any more thoughts on this would be great.

    If you are passing the values of the parameters around in your program you might want to consider using the OO interface to CGI and pass the CGI object around instead and use $cgi->param() in the subroutines. This has the side benefit that if you find that you require more parameters in a subroutine you won't need to change the arguments.
