I've looked through the various and very elegant macro solutions proposed for
this problem.
What are the benefits of using the SET statement in a data step vs. writing a
PROC APPEND task (or PROC DATASETS with the APPEND statement) in a macro? From
my perspective, and depending on the number of observations to be processed, an
append is preferable to the SET statement in a data step.
SAS documentation asserts that concatenation is more efficient in V8 than it
was in V6.
Comments?
Thanks, Andrew
