Flash Wizards: flash actionscript question ... anyone feel like saving my day? Easy!
 

Any flash actionscript (or javascript, I hear it's pretty similar) wizards who can tell me how to chop a set number of characters from the end of a string? For example, say I have a dynamic string containing "test_phrase_one" and I want to remove the last 4 charachters so it reads "test_phrase" using actionscript.

Seems this should be really simple, if anyone is bored and feels like helping it would be greatly appreciated.

Thanks :)

A snippet of code pointing in the write direction is all I'm asking for, just to clarify.
