Chapter 8 Programming

3. This command can be used in combination with conditional jumps and count

jumps.

4. If there is no Lbl-statement whose value matches that specified by the Goto-

statement, an error (Go ERROR) occurs.

Example: ? → A : ? → B : Lbl 1 :

? → X : A × X + B ^

Goto 1

This program calculates

y = AX + B for as many values for each variable that you

want to input. To quit execution of this program, press A.

Isz

Function: This command is a count jump that increments 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] Isz A : Increments the value assigned to variable A by 1.

Description:

This command increments 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 (_).

⇒ (Jump Code)

Function: This code is used to set up conditions for a conditional jump. The jump is

executed whenever the conditions are false.

Parameters:

left side/right side: variable (A to Z), numeric constant, variable expression (such as:

A × 2)

relational operator: =,
