Aggregation Function

[SUBSCRIBE SPSSX-JohnF]

As best I can tell after searching the listserve\newsgroup for variable limitations using the aggregate function my efforts to aggregate a data set of less than 150 variables and no more than 3 or 4 break variables should be easy, does that sound right?  

By the way does anyone know what the variable limit is on aggregating?

Thanks

There are no documented limits for AGGREGATE.  With zillions of break variables and groups, you could run out of memory, but that would only happen with vastly larger problems than you have.

Consider:

MATRIX.
SAVE TRUNC(UNIFORM(20000,1500)*10)/OUTFILE * /VARIABLES X0001 TO X1500.
END MATRIX.
AGGREGATE OUTFILE * / BREAK X0001 TO X0020/ Z0021 TO Z1500=MEAN(X0021 TO
X1500).

 There is memory for only 18381 cases in the aggregated file.

* However No problem.
SORT CASES BY  X0001 TO X0020.
AGGREGATE OUTFILE * /PRESORTED/ BREAK X0001 TO X0020/ Z0021 TO
Z1500=MEAN(X0021 TO X1500).
