A process cannot modify its parent's environment.  You can set environment 
variables to be used during the Perl program that are visible to the Perl 
program's child processes, through the %ENV hash.  But you cannot change 
your parent's environment.

Perl offers built-in support for environment variables via the %ENV  
hash:


% cat foo.pl
$ENV{FOO} = "foo";
system q(echo $FOO);
% perl foo.pl
foo

%ENV is documented in perlvar.

See also the Env standard module, which is specially handy for PATH- 
like variables.

passing variables from perl to the system

[Eliyah Kilada]

Hi,
Do anyone know how to pass the perl variables to the system in order to 
be used later?!


I though of passing them as enviromental variables using
system (export, "sys_var_name","= $perl_var_name" );

but it doesn't work -:(

Any help is highly appreciated!

Best Regards,
Eliyah
