SECTION 8 COMMAND DESCRIPTIONS

BRANCHING COMMANDS

Branching Commands cause the program to go to a specific line number or label. This sometimes will

occur if a condition exists, like an input being activated. The most common use will be to have a machine

operator activate a switch before the machine begins operation. Another use of these types of commands

would be for a program to continuously go from the bottom of the program back to the top of the program.

The Branching Commands cause the program to ‘branch’ to another part of the program based on a set of

conditions, like a switch being pressed, a register value equal to a number, a bit set, or many other

conditions.

GOSUB COMMAND

When the Gosub Command is implemented, the program will go to the specified line and then the

Return Command will send it back to the line below the original Gosub Command. This must be

used in conjunction with the Return Command.

This sample will cause the next instruction to go to the label Function 2, execute the lines 68

through 74, and then return to line 15..

Line Command Parameter 1 Parameter 2 Comments

14 Gosub FUNCTION2

67 Label FUNCTION2

75 Return Returns to Line 15

GOTO COMMAND

The Goto Command causes the program to go directly to the specified line. This line can be

described by a Line Number, a Register Value, or a Label. When using a Register Value, you must

make sure that there is a value stored in that Register. If there is a value, for example 10, then

this command will cause the program to jump to line 10 for the next command.

This sample will cause the next instruction to go to the Label Top.

Line Command Parameter 1 Parameter 2 Comments

14 Goto TOP

IF BIT COMMAND

The IF BIT COMMAND is a conditional statement used to execute another command based on

whether or not a certain Input condition is met.

Line Command Parameter 1 Parameter 2 Comments

1 If I1 = 0 Then TOP Else CONTINUE

IF REGISTER COMMAND

The IF REGISTER COMMAND is a conditional statement used to execute another command

based on whether or not a certain Register condition is met.

Line Command Parameter 1 Parameter 2 Comments

1 If R1 = 0 Then TOP Else CONTINUE

LABEL COMMAND

The LABEL command is simply used to label a line. As mentioned before, labels are commonly

used with branching statements.

Line Command Parameter 1 Parameter 2 Comments

1 Label TOP
