First try: 

gen cc = substr(cntrno,1,2) 

keep if cc == "AG" | cc == "AI" | <etc> 

If the -keep- is still too long, then 

gen tag1 = cc == "AG" | cc == "AI" | <etc>
gen tag2 = cc == "GB" | cc == <etc> 
keep if tag1 | tag2 

etc. 

If this strategy fails, see the FAQ:

I was using the following command, but the Stata output said:

expression too long
r(130);

end of do-file
r(130);

Any idea of how to get round this? Many thanks.

The command was (just one command):
