CUNDEF

The CUNDEF command generates a #undef compiler directive for C output.

identifier_name

is the name of the identifier affected by the #undef directive.

The DDL compiler generates a #undef statement in C output without checking

whether the identifier name was previously defined.

It is your responsibility to use proper identifiers with the CUNDEF command.
