Re: perl doesn't like variable

You need to declare the variable before usage. Try:

my $counter = 0;
# (comment-out added): use vars qw($counter);
[download]

or (From davido)

use vars qw($counter);
$counter = 0;
[download]

Update: Per davido's comment, I've modified my answer.

You need to declare the variable. Try: `my $counter = 0;` Why? He is properly declaring his variable to be a package global, and that is perfectly legit under strictures. It would be a mistake to try to also declare it to be a lexical variable, as that would create two separate variables. His problem is that he initialized $counter before declaring it. Here is his code: `$counter = 0; use vars qw($counter);` [download] The proper sequence of events is to declare the variable, and then start using it (or initialize it), like this: `use vars qw($counter); $counter = 0;` [download] HTH.

Good catch. Chalk that up to tunnel vision on my part. I saw the usage w/o declaration and didn't even look any further. -jbWare	[reply]

Thanks! I did that and now it does not increment within the loop. Do I need to declare it somewhere within the block? Thanks Jim jamaas btinternet com	[reply]


Do you know where your variables are?
