Heya Ryan,
RCC> Here is something to get you started...
>>> expression-string: "2 + 2"
RCC> == "2 + 2"
>>> do load expression-string
RCC> == 4
Mmm quite obvious really.
expression-string: "2 / 0"
either error? try [expresult: do load expression-string] [
Print "Bum expression man, get some skillz!"
][
Print rejoin ["The result was: " expresult]
]
Sweet!
