XPATtern
Command :MACHine{1|2}:SLISt:XPATtern
<label_name>,<label_pattern>
The XPATtern command allows you to construct a pattern recognizer term
for the X marker which is then used with the XSEarch criteria when moving
the marker on patterns. Since this command deals with only one label at a
time, a complete specification could require several invocations.
When the value of a pattern is expressed in binary, it represents the bit
values for the label inside the pattern recognizer term. In whatever base is
used, the value must be between 0 and 2
more than 32 bits. Because the <label_pattern> parameter may contain
don't cares, it is handled as a string of characters rather than a number.
string of up to 6 alphanumeric characters
