The software processes
all of the observations in the entire data set unless you specify
a range of observations with the STARTOBS= or ENDOBS= options. If
the STARTOBS= option is used without the ENDOBS= option, the implied
value of ENDOBS= is the end of the data set. When both options are
used together, the value of ENDOBS= must be greater than the value
of STARTOBS=.
In contrast to the Base
SAS software options FIRSTOBS= and OBS=, the STARTOBS= and ENDOBS=
SPD Server options can be used for WHERE clause processing in addition
to table input operations. When ENDOBS= is used in a WHERE expression,
the ENDOBS= value represents the last observation to process, rather
than the number of observations to return.
