Thanks in advance.
First off, saying $a = s/^/_/g; means run this substitute against $_ and assign the number of replacements made to $a. What you want to do is bind the substitute command to $a like this: $a =~ s/^/_/g;. Secondly, the ^ character has special meaning in regexes: start of line. To get rid of this special meaning you must escape the character: $a =~ s/\^/_/g;. There are other characters you need to be careful with: +*$()\. Read "perldoc perlre" for more information. ^ is one of the special characters in regexes; it means . -- Today is Setting Orange the 35th day of Chaos in the YOLD 3168 P'tang!
