Ok thanks wags...that explains it. Now don't flame me hehe but...
$value =~ s/\+/ /g; is saying substitute any "+" with a space...right? Again thanks everyone for your help in advance.

([^=]+) goes into $1 (.*) goes into $2 Unless the parens are escaped(ie, \( ), you count from the left where the first ( is $1, 2nd is $2 ,etc. They can be nested if necessary.

Ok, Sorry guys I am trying to get my head around this... $pair=~m/([^=]+)=(.*)/) The "m" means treat string as multiple lines Then we are grouping with a parenthesis and the "^=" is saying matching anything up to the "=" The "+" is a quantifier saying that must match 1 or more times... Then the the rest is saying match anything after the "=" I guess my question is am I right? And I still am not sure where it is saying to assign the first match to variable $1 and then the rest to variable $2 Thanks in advance...

Wrong. This says: Match anything (of at least one character) up to but not including '=' and put it in the special variable $1; then match the '='; then match what's left (possibly nothing) and put it in the special variable $2. -- felix -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
