    returning values from scripts

    Hi all.
    I need to run a script from another script, and to catch a value the first returns. for example :
    a.pl :
    .
    .
    .
    my $ret_num = 17;
    exit ($ret_num);
    ------------------------------------------
    calling the script from another script:
    my $temp_num = system(a.pl);

    I would like to catch 17 in $temp_num ... but it doesnt work.
    any idea?

    thanks a lot, Moshe.

    Hi, welcome to the forums.

    Haven't checked this, but try checking the $? variable. Thats normally the last exit code.

    The funny numbers, I suspect, are the proper exit codes. Usually -1 or 0.

    To be honest, I don't think exit codes are meant to be used like this. Wouldn't it be simpler to include the file rather than execute it, and return the number that way?

    Yeah, I guess this is the only thing I can think about ... a bit ugly but I have no other ideas ...

    Thanks a lot again ... greetings from Israel
