A lot easier just to 

. drop if missing(date, publication) 

Please do not send .vcf to Statalist.

could anyone point me to how to resolve the following situation during
the stage of data cleaning.

I have an excert from a data bank with several lines of data per real
world case.
The data table looks like that:

caseid     date                stage             publication
1            01oct1990       indictment
1                                    indictment    Journal, No 3, page
10
2           10may1995       indictment
2                                    indictment    Journal, No 1, page 5

Either the date or the publication reference is missing for each case in
one of the stata case lines.
I'd like to fill in these missing data and then drop the duplicate lines
of data.
