What are you missing?You can write it as your way with no problem usually.
But don't do this under mod_perl,otherwise you'll get lost really.
You may write them like:
use strict;
my $ab=27; # don't use $a,$b as variable's name since both $a and $b are used
by perl's 'sort' function by default.
doit($ab); # pass $ab to the subroutine distinctly
sub doit {
my $s = shift;
print "$s\n";
}
My only problem was that the variable in the subroutine was not declared
with my nor our, not on purpose. I didn't know that you could do that
when using strict. I always use my or our, so I hadn't encounter this
behaviour yet.
Thank you.
