Re: st: prob regarding -strpos-

[Nick Cox <njcoxstata@gmail.com>]

This does indeed seem surprising but right now I can't check whether  
it's reproducible. In any case you would need to use different  
machinery (extended macro functions) to check for presence of a  
substring in strings longer than 244 characters given limits  
documented at -help limits- and in the manual.
