The DEFINE MACRO command defines or redefines a macro command in the
specified macro buffer. Macros must be disabled and unlinked before they can
be redefined. The macro command can be redefined by reissuing this command,
and the new macro will replace the old and all outstanding responses will be
discarded. The exception flag is reset each time this command is processed.
