When you read multiple records from a direct access data file, the
records are laminated together along a new first dimension before
they are assigned to the OAT shared variable. For example, assume
you read three records (character vectors) from the following data file:

a 3 x 5 character matrix.
The new first dimension represents the number of records read. You
can specify each individual record by indexing the new dimension.
