Hi, Patrick.  There's now such thing as a stupid newbie question...

Try

	aPoint := Scanner new scanTokens: aPoint


This should give you an array with <number> #@ <number>, which you can then check for validity.  A more powerful thing to do is Compiler evaluate: <string>, but this will more easily cause errors.

Hope this helps
