Data CP

[Function] This command is used between SLCT and EDSL commands to execute the subsequent

commands up to the next WXXX command or an OTHE or EDSL command when the

comparison result of the content of the variable specified in operand 1 with the value

specified in operand 2 satisfies the condition.

WHXX

Operand 1 = Operand 2

Operand 1  Operand 2

Operand 1 > Operand 2

Operand 1  Operand 2

Operand 1 < Operand 2

Operand 1  Operand 2

[Example 1] LET 1 20 Assign 20 to variable 1.

LET 2 10 Assign 10 to variable 2.

SLCT Execute multi-branching.

WHEQ 1 10

(1)

(1) will be executed if the content of variable 1 is 10.

Since variable 1 contains 20, however, the next

condition will be referenced.

WHGT 1 *2 This command will be executed if the content of variable

1 is greater than the content of variable 2.

Since variable 1 (= 20) > variable 2 (=10), (2) will be

executed.

(2)

OTHE This command will be executed if none of the conditions

are satisfied. In this example, since (2) was executed,

(3) will not be executed.

(3)

EDSL

(4)

The processing will move here if any of the conditions

was satisfied and the applicable command executed. In

this example, (2) and (4) will be executed.

* If multiple conditions are likely to be satisfied, remember that the first WXXX will become valid and any

subsequent commands will not be executed. Therefore, state from the command with the most difficult

condition or highest priority.
