Calling a perl script with a perl script

[Hubert Ian M. Tabug]

Hi,

        Given that I have a perl script main.pl, and I want main.pl to "use/call" the 
script testprog.pl, and store testprog.pl's output into a variable that can be used 
within main.pl. How do I go about doing it? Your help would be greatly appreciated.

Thanks,
Hubert
