The Label statement

Introduction

The Label statement is usually used in conjunction with a Go to statement, to perform simple loops in a procedure. It can also be used without a Go to statement, to simply show the start of a new section of a procedure.

Within the procedure, the statements after a label are indented to show that it is the start of a new section of the procedure.

Example

The following example shows a Label statement used in conjunction with a Go to statement, to perform a simple loop which executes continually throughout the test.

This same logic could also have been implemented using a Repeat statement.

More information

Labels within a procedure must have unique names, to ensure that a Go to statement can differentiate between them. If you try and define a procedure with multiple labels with the same name, an error will be generated when you check the procedure for errors or exit the procedure editor.

A Label statement can be inside a container If statement or Repeat statement, so that a Go to statement can jump into the container and execute from there. However, this will result in quite complex logic within the procedure, so I don't recommend that you do this!
