Internal Error # 1101
 Invalid parameter to _xpushf
----------------------------------------------------------------------------------

 Internal Error 1101 is caused by calling the internal _xpushf with a
 parameter that is not a valid field.  _xpushf is called by fieldGet(), but
 fieldGet() theoretically should not be able to cause a 1101 because it
 checks its parameter, and doesn't call _xpushf if the parameter is out of
 range.
