Assembly Language
.UNDEF
Syntax
.UNDEF symbol
Description
With the .UNDEF directive you can undefine a substitution string that was previously defined with the .DEFINE directive. The
substitution string associated with symbol is released, and symbol will no longer represent a valid .DEFINE substitution.
The assembler issues a warning if you redefine an existing symbol.
Example
.UNDEF LEN
Undefines the LEN substitution string that was previously defined with the .DEFINE directive.
