undef

Undefine a Debugger Macro

ABBREVIATION
u{ndef}

FORMATS
Format 1: undef MACRO-NAME
Format 2: undef *

DESCRIPTION
The undef command drops debugger macro definitions, which are defined with the define command. After undef removes the definition, any further attempts to use the macro name produce a diagnostic message.

Format 1: Format 1 removes a single definition specified by MACRO-NAME.

Format 2: Format 2 removes all debugger macro definitions.

A debugger macro can be redefined by issuing another define command for the same macro, but with new substitution text. You do not need to use the undef command on a macro before redefining it.

EXAMPLES

undef mac1
undefines the debugger macro mac1 previously defined with the define command.

undef *
undefines all debugger macros.

SYSTEM DEPENDENCIES
none

COMMAND CAN BE ISSUED FROM

PROFILE yes
configuration file no

Unsuccessful: 1
