The solution could be as easy as
***********
bysort block: gen bldg=_n
***********

Subject: st: number generation
I would like to generate a method to number buildings in sequence, but
restart the sequence in accordance with a group. For example I have
the following nomenclature
(block) (round) (plot) (bldg)
005 050 010 xxx
005 050 020 xxx
005 050 030 xxx
005 050 040 xxx ...
005 050 150 xxx ...
005 060 010 xxx ...
010 010 010 xxx ...
where xxx represents a unique object identifier. I'm thinking to use
gen or egen with a cond() qualifier, but how to set the parameters for
the unique object identifier such that it returns sets of the
following structure
005 050 010 001
005 050 010 002
005 050 010 003 ...
005 050 010 999
thank you,
Ty
