AXimum|MINimum|DEFault
Parameter(s) Distance:
The program data syntax for <Distance> is
defined as a <numeric_value> element followed
by an optional <SUFFIX PROGRAM DATA>
element. The allowed <SUFFIX PROGRAM
DATA> element is M. The <Distance> special
forms MINimum, MAXimum and DEFault are
accepted on input.
MINimum allows to set the instrument to the
smallest supported value.
MAXimum allows to set the instrument to the
greatest supported value.
