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.
Syntax:
Parameters:
left side/right side: variable (A to Z), numeric constant, variable expression (such as:
A × 2)
