NULL

Purpose

Placeholder statement.

Syntax

Description

The NULL statement performs no action, but is used to provide null THEN or ELSE clauses in IF statements, null ON-units in ON statements, or to allow multiple label prefixes.

Example

A:; 
B:; 
C: ON ENDPAGE (F);

In this example, the ON statement has a null ON-unit and is preceded by two labeled null statements, effectively giving the ON statement three labels. However, these labels do not compare equally because they designate different statements.

Restrictions

None.
