I've just read that bit of the dictionary and I'm equally surprised. I also think I must have completely misunderstood it, because I can't see how it can work. The value of a script local variable (unless it's predefined using an '=' construction) is undefined until a script is run, and is then only defined when an executing script puts something into the variable. A script can only be run when the program is executing. When the program containing the script quits, any information in variables, global or local, is lost because one can't normally save an executable stack outside the IDE (yes, I know about splash stacks and such, but the principle is correct). So next time the script is compiled, we **must** be back at square one, and the value of local variables **cannot** be maintained. What's wrong with this thinking?
