085-2008: When PROC APPEND May Make More …

1 Paper 085-2008 when PROC APPEND May make more Sense Than the DATA STEPD avid W. Carr, ICON Clinical Research, Redwood City, CAABSTRACTV irtually all SAS programmers (with apologies to diehard SQL codeslingers) tend to use a simple SET statement in theDATA STEP when concatenating two or more datasets in their programs. Use of the SET statement is generallythe most logical and practical approach becausethe required code is typically very succinct and the process in most instances involves concatenation of only two datasets. However for those occasions when the SAS programming job either requires concatenation of a large number of datasets or concatenation of very large datasets (regardless of the number), the APPEND procedure is oftentimes a more sensible alternative. The purpose of this paper is to present examples of cases in which PROC APPEND may be a better choice than the SET statement in the DATA STEP and to provide some justificationfor why the APPEND procedure is a viable option.
