Need Perl script to execute from another.

[beelow]

Hi,

I am new with PERL programming.
I have a question. Is it possible to call a Perl script from an another script. The problem is how to get a response from the script?

Any help will be appreciated.

This will call a new perl process, and may be more expensive on the

system. On the other hand I can do

But How do I get the response of the script.

Probably the dimpliest way is to make called script a module and run it
using either 'use' or 'require'.
If you care about speed, consider using do 'filename.pl', which will avoid firing up a new Perl interpreter.

I think you can do the following;
1. backticks: $retVal = `perl somePerlScript.pl `;
2. system() call
3. eval
The eval can be accomplished by slurping the other file into a string (or a list of strings), then 'eval'ing the strings

#!/usr/bin/perl
open PERLFILE, "<somePerlScript.pl";
undef $/;   # this allows me to slurp the file, ignoring newlines
my $program = <PERLFILE>;
eval $program;

4. do:

do 'somePerlScript.pl'
