Dear Monks, I gained some additional wisdom about the function 'do' which I would like to share.

I used the do function in the first script to execute the second script in the same context (shared memory without creating another process by using system(..)). Though, I had to pass some arguments to the second script. do "2.pl $arg1" does not work.

Finally I came to know that if we want to pass argument to the second script, we can exploit the idea that @ARGV will be visible to the second script. I achieved the goal as below: 

use my_module;

print "@my_var\n"; # prints 1..10
change_var();
print "@my_var\n"; # prints 20..30
{ # using local to supress @ARGV
    local @ARGV = ($arg1, $arg2...); # $arg1, $arg2... are the argumen
+ts to be passed
    
    do "2.pl";
}
exit;

Now, in 2.pl I can get these arguments using shift.

Regards,

--Anupam
