You should not call lexical variables $a and $b because this interferes
with the $a and $b
Hello,
I've started experimenting with the use of subroutines in place of large,
repeating blocks of code in a few of my programs. Without exception, these
subroutines require variables defined outside of the subroutine. Unless I'm
mistaken, the only way to make these variables available within

I'm using these statements in my main program:

print join(, map { qq[td$_/td] }

When I use the debugger, I find that order is
undefined! When I use the browser to view the page,
the value of undef is confirmed.

In one of my scripts I have lots of variables to declare. I wanted to type them in
groups instead of one long line but I think dividing my lines trough the use of the
ENTER key stops the script from working. (Although when I check the syntax through
perl - c script.cgi it gives me OK).

usual method:
my $variable;
but I am trying to get what (if anything) is being done differently by

Thanks!
