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.
Jens Lauritsen EpiData Association ps. The revised web site www.epidata.dk is still in construction. I will give a notice when the new design has been completely implemented.
all well what ends well - many thanks. It is working fine an saving the duplicates. Once fixed we emphasize more on the first option to avoid this at the data entry stage. Bests Max
