Programming Chapter 8
Description:
1. This command repeats the commands contained in the loop as long as its condi-
tion is true (non-zero). When the condition becomes false (0), execution pro-
ceeds from the statement following the WhileEnd-statement.
2. Since the condition comes after the While-statement, the condition is tested
(checked) before the commands inside the loop are executed.
Example: 10 → A_
While A > 0_
A – 1 → A_
”GOOD”_
WhileEnd

Break
Function: This command breaks execution of a loop and continues from the next
command following the loop.
Syntax: Break _
Description:
1. This command breaks execution of a loop and continues from the next command
following the loop.
2. This command can be used to break execution of a For-statement, Do-state-
ment, and While-statement.
Example: While A>0_
If A > 2_
Then Break_
IfEnd_
WhileEnd_
A ^ ← Executed after Break
Prog
Function: This command specifies execution of another program as a subroutine. In
the RUN Mode, this command executes a new program.
Syntax: Prog ”file name” _
Example: Prog ”ABC” _
Description:
1. Even when this command is located inside of a loop, its execution immediately
breaks the loop and launches the subroutine.
2. This command can be used as many times as necessary inside of a main routine
to call up independent subroutines to perform specific tasks.
