XPATtern

Command:MACHine{12}: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 232 − 1, since a label may not have 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.

<label_name> string of up to 6 alphanumeric characters

<label_pattern> "{#B{01X} . . . #Q{01234567X} . . . #H{0123456789ABCDEFX} . . . {0123456789} . . . }"
