specifies the number of rows to hold in memory input into
SAS. The value must be positive.
Choosing the optimum value for the READBUFF= option requires
a detailed knowledge of the data that is returned from the information map
and of the environment in which the SAS session runs. Buffering data reads
can decrease network activities and increase performance. However, higher
values for READBUFF= use more memory. In addition, if too many rows are selected
at once, then the rows that are returned to the SAS application might be out
of date. For example, if someone else modifies the rows after they are read,
you do not see the changes.
