⇒ (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:
True
<left side> <relational operator> <right side> ⇒ <statement>
_
:
^
<statement>
False
Parameters:
•
left side/right side: variable (A to Z, r , θ ), numeric constant, variable expression (such as: A × 2)
• relational operator: =, ≠ , >, <, ≥ , ≤ (page 8-20)
Description:
• 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.
• 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 command ( ^), or carriage return ( _).
Menu
Function: Creates a branching menu in a program.
Syntax: Menu "<string (menu name)>", "<string (branch name) 1>", <value or variable 1>,
"<string (branch name) 2>" ,<value or variable 2>, ... , "<string (branch name)
n >", <value or
variable n >
Parameters: value (0 to 9), variable (A to Z,
r , θ )
Description:
• Each "<string (branch name)
n >" ,<value or variable n > part is a branch set, and the entire
branch set must be included.
• From two to nine branching sets can be included. An error occurs when there is only one or
more than nine branching sets.
• Selecting a branch on the menu while the program is running jumps to the same type of label
(Lbl
n ) as the one used in combination with the Goto command. Specifying “"OK", 3” for the
“"<string (branch name)
n >", <value or variable n >” part specifies a jump to Lbl 3.
Example: Lbl 2 _
Menu "IS IT DONE?", "OK", 1, "EXIT", 2 _
Lbl 1 _
"IT’S DONE !"
