status.i4.v = input_field_enable_c(identifier.g.v)

	This routine will enable an input field which was disabled by an
	earlier call to input_field_disable_c.

	identifier	identifier of desired field whose type depends on
			the most recent call to input_field_set_id_type_c
			(INPUT_FIELD_BY_ID -> use four byte ID value returned
					      by a prior call to
					      input_field_create_c (default),
			 INPUT_FIELD_BY_HANDLE -> use ASCII handle string)
			(Note:  If the identifier type is INPUT_FIELD_BY_ID
			 and a negated window ID or a value of WMNGR_BACKGROUND
			 is passed, all input fields in that window will be
