θ
[Example] Isz A : Increments the value assigned to variable A by 1.

Description:
• The conditional jump compares the contents of two variables or the results of two
expressions, and a decision is made whether or not to execute the jump based on the
results of the comparison.
• If the comparison returns a true result, execution continues with the statement following
the
⇒
command. If the comparison returns a false result, execution jumps to the
statements following the multi-statement command (:), display command (
^
), or carriage
return (
_
).
