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
