- The maximum acceptable value for the parameter (if greater than

The DEFPARAMENUM<N> macro is similar, but instead of the minumum and maximum
arguments, it contains a list of <N> allowed strings, corresponding to
integer values 0..<N>-1. Note that the default argument needs to be
specified as one of the allowed strings, rather than an integer value.
Be sure to add an entry to invoke.texi summarizing the parameter. */
