The GOTO statement is used to perform an unconditional branch to another section of code. It references a label that must appear in the code.
Labels are written as a name followed by a colon. Labels must appear on their own lines and they may be commented.
You can only branch within a program, event, function, or subroutine. The GOTO statement and the label must be within the same program block. The GOTO statement can be compared to the conditional branching statements, IF..THEN and SELECT CASE.
Syntax
GOTO <program label>
<program label>:
Availability
All versions
Scope
Task
Limitations
- Write only.
- The label must appear on a line of its own.
- Labels may not be repeated within a task.
- A GOTO branch must reference a label within the same program block (PROGRAM…END PROGRAM, SUB…END SUB, FUNCTION…END FUNCTION, and ONEVENT…END ONEVENT).
Examples
Program <code> GOTO Reference1 <code> Reference1: <code to be executed after GOTO> End Program
