Re: Removing characters

tr modifies the string it works on, and returns the number of substitutions.

BTW when you want to join two strings, use a dot ., not a plus +. (This is called "concatenation").

You can use tr, but you have to discard its return value. `my $str = "ab c,d.e"; $str =~ tr/ ,.//; # here $str is "abcde"` [download] So you need to use the modified string after the tr. And don't try to stuff it all in one line ;-) (Update: fixed match operator)	[reply] [d/l]
