can you check for assignment?

Is it possible to check if a *local* variable has been assigned a value without crashing the program if false, as in the following example? procedure get_this(integer info) integer last_time if info = last_time then do_this else do_that end if last_time = info end procedure This proc would crash on the *first* use. I tried if integer(last_time) which also crashes. I don't really want to declare last_time as global because I have far too many globals already (which I'm trying to tidy up). Does declaring last_time invalidate my cause anyway, i.e. will it's value be cleared everytime the proc is run? Thanks Terry
