You probably can do what you want by using -real- to generate the numeric
variable -newzip- from -zip-, reformat as integer, and then use the -egen-
function,
-eqany newzip, values(12345, 12456, 234,...), to create a 0-1 variable to be
used with -keep-.

Subject: st: Formatting Columns in Tabstat
Hi,
Hope someone can help me with this.
I have a dataset of households in various zip codes. I want to keep only
those hholds that are in 700 particular zip codes that I've identified. The
logical way to do this in stata is to write a command that looks like this:
keep if zip=="12345" | zip=="12456" | zip=="00234" | zip==..............
There would be about 700 "or" conditions.
The problem is, Stata doesn't allow this many "OR" conditions in that
statement. This command works fine if I only put in 10 or 20 zips. It
gives me an error saying "too many literals" if I put in all 700 zips in my
list.
Is there any other way for me to perform this operation?
This is doable in SAS, since there's a command:
if in (insert list of zip codes here);
Perhaps there's an analogous command in Stata?
Thanks in advance for your help.
