SPD Engine LIBNAME Statement Options

ENDOBS= LIBNAME Statement Option

Specifies the end observation number in a user-defined range of observations to be processed.

Used with:	STARTOBS=
Corresponding data set option:	ENDOBS=
Default:	the last observation in the data set
Restriction:	use ENDOBS= with input data sets only
Restriction:	cannot be used with OBS= system and data set option or FIRSTOBS= system and data set option

Syntax

ENDOBS=n

n: is the number of the end observation.

Details

By default, the SPD Engine processes all of the observations in the entire data set unless you specify a range of observations with the STARTOBS= and 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 default Base SAS engine option FIRSTOBS=, the STARTOBS= and ENDOBS= SPD Engine system options can be used in the LIBNAME statement.

Note: The OBS= system option and the OBS= data set option cannot be used with STARTOBS= or ENDOBS= data set or LIBNAME options. [cautionend]

(See SPD Engine Data Set Options for information about using the ENDOBS= data set option in WHERE processing.)

Example

The following example shows that the STARTOBS= and ENDOBS= options subset the data before the WHERE clause executes. The example prints the four observations that were qualified by the WHERE expression (age >13 in PROC PRINT). The four observations are out of the five observations that were processed from the input data set:

libname growth spde 'D:\SchoolAge' endobs=5;
data growth.teens;
   input Name $ Sex $ Age Height Weight;
datalines;
Alfred M 14 69.0 112.5
Carol F 14 62.8 102.5
James M 13 57.3 83.0
Janet F 15 62.5 112.5
Judy F 14 64.3 90.0
Philip M 16 72.0 150.0
William M 15 66.5 112.0
; 

proc print data=growth.teens;
   where age >13;
run;

The output is shown:
