accessing variables declared in another perl script

Shell Programming and Scripting

Hi all,

I have a perl script which declares two variables and calls another perl script which accesses those variables. But I am unable to access the variables in the called script. My script is as follows:

my $ENV{a}="20";
system("perl called.pl");

and my called.pl contains:

print "$ENV{a}\n";

My problem is that a variable declaration script reads the values from a config file and then I calll that variable declaration script from my main script which access the variables. I am declaring all the variables as Environment variables.

Please help me.

Thanks,

guru

As I said, I used exactly the same case you provided but I got the result you asked for. I'm not sure what your problem is exactly.

[bernardchan@bernardchan shm]$ cat a.pl
$ENV{a}="20";
system("perl called.pl");
[bernardchan@bernardchan shm]$ cat called.pl
print "$ENV{a}\n";
[bernardchan@bernardchan shm]$ perl -w a.pl
20
