Increment <var> by 1. If the result is zero, skip the next statement.

Appears to be bug-free. Note that "Isz <var>:0" is one byte shorter than "<var> + 1 -> <var>".

This command is intended to be used to make counting loops shorter, as follows:

  (-)5 -> A   ; (-) is the CTF token for minus
  Lbl 0
    "HELLO WORLD"
    Isz A
  Goto 0

which would output "HELLO WORLD" five times. On the fifth time, A would become zero, so the Goto could be skipped.
