Use information: Store status (applies only to reals and ASCII)
0=store the data value(s) provided
1=store the bad value representation instead
When data type is an array, the store status applies to the whole
array. The bad value representations are NaN for real values and
question mark strings for ASCII.
Content of the field "parameter array pointer/size" depends on
data-type specification. See paragraph 4.7.1 for an explanation of
this field's use with single parameters and with parameter arrays.
This message requires the requesting ACP be connected to its
ACIDP.
This message may be used by one ACP to turn on another ACP by
setting the other's ACIDP PPS parameter to ON.
