The server processes
the entire table by default unless you specify a range of rows. You
can specify a range using the macro variables SPDSSOBS and SPDSEOBS,
or you can use the table options, STARTOBS= and ENDOBS=.
If you use the range start
macro variable SPDSSOBS without specifying an end range value using the SPDSEOBS macro variable,
the server processes to the last row in the table. If you specify values for both
SPDSSOBS and SPDSEOBS macro variables, the value of SPDSEOBS must be greater than
SPDSSOBS. The SPDSSOBS and SPDSEOBS macro variables specify ranges for table input
processing as well as
WHERE clause processing.
