Independently of that -egen, cut()- does not sound the best bet for what I guess to be your problem. Perhaps you need -round()-, -floor()- or -ceil()-. 


Martin Weiss

-egen, cut()- takes a numlist for the -at()- option, so it must respect -h limits- for -nulist: 1,600 elements.

Try this (and observe where Stata`s complaints start):

sysuse auto, clear

egen newmpg=cut(mpg), at(12/41)
drop newmpg
egen newmpg=cut(mpg), at(12(0.1)41)
drop newmpg
egen newmpg=cut(mpg), at(12(0.01)41)
drop newmpg

I am using egen with cut to divide my time in intervals:

egen newtime=cut(time), at(17000,170500....)

I there a limit for at?

Because I have many intervals and it doesn't work, so I treid to split
in two and it works.

However, now I have a problem. How to add the observation of the two
variables(because I generate two newtime for different intervals) into
one variable?
