I want to set up a state machine, in this case I am parsing a simple scripting language using regexp, and then running a segment of code, which might be another regexp, etc. I'd like to be be able to specify that code in a file... Can I feed a String like "str = a.scan(/\<cat.*?>/)" #regexp here is just an example ;) into a method or any other way and have it execute? TIA John B
