Issue in executing more than one perl script from Single perl script

Hi,
I am calling "1.pl" from "main.pl" file.
using
#main.pl
system ("perl 1.pl");

In this case it works fine.

But when I am doing
#main.pl
system ("perl 1.pl");
system ("perl 2.pl");

then it doesn't executes "1.pl" properly.
So I would like to know, is there any constraint for this? Do I need
to take any precautions for this?

Thanks,

You need to provide some symptoms if you hope for a diagnosis.

How do you know that it did not execute properly?

What did you observe?

Were any messages issued?

Why are you using system() for this? AFAIK it forks a
whole new process - a lot of overhead to go to.
Isn't this what the "require" facility is for?

FWIW

There's nothing wrong with the above code.

What kind of output were you expecting, and what did you get instead? You
need to offer a better description of the problem than "it doesn't work",
if you expect more than just random guesswork in response.

"This" being what, exactly? Perl has no problem calling system() twice; to
be blunt, it's patently absurd to think it might have such a restrictive
problem.

Using system, you start a completely new program which executes on its
own, in its own context and e.g. is not required to be a Perl program at
all.

OTOH "require" will include the Perl program code into the current
program code.
