in reply to Replacing matches within string without splitting.

Typically, leading zero printing, and other formatting is done using sprintf and friends:
perl -E '$x="2,42,1,3"; printf "%.2d ",$_ for eval("($x)") ; print +"\n"' 02 42 01 03
Update: Replaced with better example.

[Lady_Aleena]: [pad://]
[james28909]: my scratchpad
[james28909]: and like i say, is just an example, not working code, but hopefully you understand what i mean. :)
[james28909]: and like i say, it would be alot of work to get around renaming 3 subs haha
[Lady_Aleena]: Well, you would have to add the file munging and a lot more.
[james28909]: yeah but it would rename those subs xD
[Lady_Aleena]: I'd say, go back to my scratchpad, and really look at what the 3 subs are doing, then play. Meanwhile, I am going afk for about an hour +/- a few minutes.
