How do you declare a var global versus local? It seems variables a local and not static as in shell. That is, the sub does not see the vars from the calling part. So, can someone modify the snipet to make it work?
Varibles are by default global, and variable...
a.pl ------ # my $x; any diff from the next line? $x="abc";
doMe
sub doMe { $x="xyz"; print $x; #will print out xyz How can I get the "$x=abc" here w/o passing as an arg? }
You want the sub to see the $x from outside? Easy: just don't change $x's value...
What you've done here is declare a variable $x, assign it the value "abc", then assign it the value "xyz" and print it out. If you wanted "abc" you shouldn't have assigned it "xyz".
Varibles vary in perl. Don't expect them not to. (You can create a constant at compile time, but that is not a variable.)
