Hello and cheers to all,
hello
I wrote a small program and it does work, but I get this error message
every tim I run the script:
Use of uninitialized value in numeric ne (!=) at ./reverse_string.pl
line 11.
basically it is a menu and when the user type 99 as a choice, the
program ends
if like is a string the you can't do != as it is a numerical comparison
line 11 is:
while ( $line != 99){
more of the script would be handy - as it looks (at a quick glance) as if $line is null.
thanks
