&UNDEFINE Directive

To remove the definition of a preprocessor name, you can undefine the name. This is the syntax for &UNDEFINE:

SYNTAX
&UNDEFINE preprocessor-name 

The preprocessorname is the name you want to undefine.

When you use the &UNDEFINE directive, Progress warns you if the name you want to undefine was not previously defined. The &UNDEFINE directive undefines the most recently defined name within whose scope the &UNDEFINE directive resides. Once you undefine a name, you can redefine it.

The &UNDEFINE directive also undefines named include file arguments. For more information, see the "Arguments to Include Files" section.
