Calling A file

Hi ppl,

Was looking for a way to call a file
from within a subroutine - i've tried
a few different things but all to no
avail

I used the search to see if it had been
asked before - no luck.

I call the sub like this:

if (param('action') ne 'CONTACT DETAILS') {
print " ",param('action'),"<BR>";
}else {
&contact
}

And at the bottom I have this:

sub contact {

#This is where I want to call modify2.pl

}

Any ideas? - Hopefully an easy one - just
not for me

Many Thanks For Your Help
