X

 nX (Skip Right n Positions)

 The X field descriptor functions the same as the TR field
 descriptor.

 On input, X starts the next read operation after skipping "n"
 character positions.  If X is the last format item, it will have no
 effect.

 On output, X starts the next write operation after skipping the "n"
 character positions.  Intervening characters are not written over.
 If X is the last format code executed, it will have no effect.

 The position specified must be in integer in the range 1 through
 the size of the record.
