l know how to do this.
first, use the getConfg() command (l think it's that one). one of the
elements in the returning list gives you the free RAM (let's assume it's 22,
which l think is right). So if you wanted to check the size of string s:
"s"->a
getConfg()[22]->b
CopyVar #a,c
getConfg()[22]->c
Disp "Size of "&a&"is: "&string(b-c)
