The subject of your e-mail suggested you wanted a random ID, but your
e-mail asked for a consecutive ID --
egen caseid=seq()
will do the consecutive ID for you.
Cheers

Subject: st: RANDOM ID GENERATORS & BACKWARD SELECTION
All,
Two more queries I have:-
(1) How do you tell Stata to generate a case ID variable that
consecutively numbers all the cases in your dataset, starting with 1, 2,
3, ... N?
(2) Can you instruct Stata to perform a backward selection procedure
when running -xtgee-, -xtlogit- or -xtprobit-? I've failed to get it to
so far!
Yours,
