By default, the server
processes the entire table unless the user specifies a range of rows
with the STARTOBS= LIBNAME statement option or the ENDOBS= LIBNAME
statement option. If the STARTOBS= LIBNAME statement option is used
without the ENDOBS= LIBNAME statement option, the implied value of
ENDOBS= is the end of the table. When both options are used together,
the value of the ENDOBS= LIBNAME statement option must be greater
than the STARTOBS= LIBNAME statement option.
Comparisons
In contrast to the Base SAS software options FIRSTOBS= and OBS=, the STARTOBS= LIBNAME option and ENDOBS= LIBNAME
option can be used for WHERE clause processing in addition to table input operations.
Example
Specify for the server
to process only row numbers 200-500 while the LIBNAME statement is
active.
