DISKRU demonstration

This is a demonstration of how a record can be updated using a combination of DISKRU and DISKW. Here the Data Stack is used, but use of a STEM variable is equally valid.

These will always be used as a pair, with only one record being read and written at a time. DISKRU does not update the record location counter, thus enabling DISKW to overwrite the current record. (The records must be of equal length.)
