[EpiData-list] Final problem in " How to: checking for duplicate records"

Apologies for having expressed the "compare current record with previous record or next record" as list if k = ( ( k[_n-1] ) or ( k[_n-1]) )

which should have been: list if ( ( k = k[_n-1] ) or ( k = k[_n+1]) )

The aggregate (tab stat) does not have a /save option, the most efficient is to:

aggregate k /sum=x /close /notable select if n > 1 savedata "newfile.rec"

Then the newfile.rec would contain only replicates.
