I have marked the word boundaries (the places in your string that are matched by \b) with # signs: #Search#, #This# #is# #part# #of# #the# #code#. A word boundary is defined as the position in a string where a word character is NOT adjacent to ANOTHER word character. >This code removes the comma. But I am puzzeled. I thought that the first line > $word =~ s/[,\]\)\}]\b//; >would delete the comma. No, because in order for a comma to be followed by a word boundary, it would have to be followed by a word character. >Yet it was the second line that did it. > $word =~ s/\b[,\]\)\}]//; Right, because the comma IS preceded by a word boundary, because the string starts with "Search," and the word boundary is between the 'h' and the ','. -- Jeff "japhy" Pinyan [EMAIL PROTECTED] http://www.pobox.com/~japhy/ RPI Acacia brother #734 http://www.perlmonks.org/ http://www.cpan.org/ CPAN ID: PINYAN [Need a programmer?
