Jump Commands (JUMP)
Dsz
Function: This command is a count jump that decrements the value of a control
variable by 1, and then jumps if the current value of the variable is zero.
Syntax:
Parameters:
Variable Name: A to Z
[Example] Dsz B : Decrements the value assigned to variable B by 1.
Description:
This command decrements the value of a control variable by 1, and then tests (checks)
it. If the current value is non-zero, execution continues with the next statement. If the
current value is zero, execution jumps to the statement following the multi-statement
command (:), display command (
^
), or carriage return (
_
).
Example: 10
"
A : 0
"
C :
Lbl 1 : ?
"
B : B+C
"
C :
Dsz A : Goto 1 : C
÷
10
This program prompts for input of 10 values, and then calculates the
average of the input values.
Goto~Lbl
Function: This command performs an unconditional jump to a specified location.
Syntax: Goto <value or variable> ~ Lbl <value or variable>
Parameters: Value (from 0 to 9), variable (A to Z)
Description:
1. This command consists of two parts: Goto
n
(where
n
is a value from 0 to 9) and
Lbl
n
(where
n
is the value specified for Goto). This command causes program
execution to jump to the Lbl-statement whose value matches that specified by
the Goto-statement.
2. This command can be used to loop back to the beginning of a program or to jump
to any location within the program.
