REGEX and Livecode

One of the reasons Regex is useful is a lot of SQL implementations support it. I suppose in theory at least, anything you can do with Regex, you can write a function to do in Livecode, but I am not so sure you could say the opposite. It really comes down to this. There are simple one liner Regex commands that are not too difficult, that would take conditional statements inside a loop in livecode to accomplish. Someone already familiar with Regex would probably prefer Regex in that case.

We should just start calling it RadScript and be done with it. That might get the attention of the younger crowd.
