IF/SELECT

IF Statements

IF statements are the primary conditional instructions. When reached, they evaluate whether a condition is true.

If the condition is found to be true, it can execute either a Jump or Call.

How to add an "IF" instruction.

If it is not true, the instruction will occur as if the line were blank.

IF	Variable	Relational Operator	Variable	Action	Destination
IF	R[1]	=	1	Call	Program1
IF	DI[3]	=	ON	JMP	LBL[2]

Additionally, when selecting the action field, another condition can be added with the AND or OR selection.

IF	Variable	Relational Operator	Variable	Modifier	Variable	Math	Variable	Action	Destination
IF	R[1]	=	1	AND	R[2]	>	AI[10]	JMP	LBL[2]

When selecting an IF statement, the first choice to be made is the relational operator within the equation to be evaluated.

Relational Operator Types
Symbol	Name	Evalues To "True" When
=	Equal To	The left variable is equal to the right variable.
<>	Not Equals	The left variable is not equal to the right variable.
<	Less Than	The left variable is less than the right variable.
<=	Less Than or Equal To	The left variable is less than or equal to the right variable.
>	Greater Than	The left variable is greater than the right variable.
>=	Greater Than or Equal To	The left variable is greater than or equal to the right variable.
(...)	Mixed Logic

In the event the equation evaluates as true, an action will occur. The following table lists the possible actions an IF statement can take.

Action Types
Action	Destination	Description
JMP	LBL[#]	The program will jump to the labeled line and continue from there.
CALL	Program	A program is CALLED. When the called program reaches the [END] instruction, it will return to the next line after the IF statement.
Call	Program()

When wanting to make a large list of possible conditions for a single variable, you'll likely want to use the SELECT option.

SELECT	Variable	Math	Variable	Action	Destination
SELECT	R[1]	=	1	Call	Program1
		=	2	Call	Program2
		=	1	Call	Program3
	Else			JMP	LBL2
