As I don't know exactly what you are asking, I can only guess as to your meaning.
I *think* what you are asking is "how do I maintain my variables from one invocation
of the script
to the next?" The good news it, if you're using CGI.pm's html generating functions,
this is done
for you (usually). If, however, those parameters are elsewhere, then it seems to me
that you want
hidden fields to hold all of the form values. If so, this is easy. The CGI::hidden
function will
conveniently output all of the hidden fields necessary to contain your form values.
Here's a
two-line demonstration:
use CGI qw/:standard/;
print hidden( $_ ) foreach param();
Save that as 'test.pl' and run it as follows:
> perl test.pl color=red color=green name=Ovid
You should get output similar to the following (I've changed the output to show each
hidden field
on a separate line):
<input type="hidden" name="color" value="red" />
<input type="hidden" name="color" value="green" />
<input type="hidden" name="name" value="Ovid" />
Note that there is one hidden field for each paramter (a total of three), even though
only two
parameters, 'color' and 'name', were supplied. And yes, the param() function only
returns the
names of the two parameters, not a list comprised of qw/ color color name /.
Cheers,

Someone asked me how to count to 10 in Perl:
push@A,$_ for reverse q.e...q.n.;for(@A){$_=unpack(q|c|,$_);@a=split//;
shift@a;shift@a if $a[$[]eq$[;$_=join q||,@a};print $_,$/for reverse @A
