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
