Programming Chapter 8
Description:
1. 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.
2. 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 com-
mand (^), or carriage return (_).
Example: Lbl 1 : ? → A :
A > 0 ⇒
A ^
Goto 1
With this program, inputting a value of zero or greater calculates and displays the
square root of the input value. Inputting a value less than zero returns to the input
prompt without calculating anything.
