st: Interval Tabbing?

[Rachel <academicgirl@gmail.com>]

What I'm looking to do is put a histogram in table form: That is, I'd
like a table showing me how many (and what percentage) of a variable
falls within intervals whose width I specify.

So for example, if X has values 2,3,5,7, and I specified an interval
of width for, the resulting table would look something like:

X range   Perc
0-4         50%
>4-8         50%
8-12          0%

Is there any Stata command (or user-written module) that can do this?

Thanks,
Rachel
