You want to change "3*foo" to "3 * foo", right? Well then, there are a couple problems with your regex. First, the (?=...) at the beginning is a look-AHEAD. You want a look-BEHIND, and you only need to look behind for one character. The character class [A-z|0-9] doesn't do what you might think. [A-z] contains all of A-Z, a-z, but also those characters whose ASCII values are between Z's (90) and a's (97). The | is not used in a character class for alternation, either. I think the regex you want is: s/(?<=[A-Za-z0-9])\*(?=[A-Za-z])/ * /g; You don't want the quotes on the right-hand side; they're not necessary. -- Jeff "japhy" Pinyan [EMAIL PROTECTED] http://www.pobox.com/~japhy/ RPI Acacia brother #734 http://www.perlmonks.org/ http://www.cpan.org/ <stu> what does y/// stand for? <tenderpuss> why, yansliterate of course.
