For me there is not errors in your lines.
Maybe there is something in the data. Try:
bys faccode pat_mrn admit_datetime discharge_datetime: count
RA

Asunto: st: what's wrong with this statement?
I've done this many times (in the past) to identify duplicate records;
I've typed and retyped this several times. What's going wrong?
. bys faccode pat_mrn admit_datetime discharge_datetime: gen dups=_N
. tab dups
variable dups not found
r(111);
Notice, the first line does NOT produce an error. However, it also does
not produce a new variable!
Thanks in advance for pointing out what must be an obvious error.
Jeph
