Re: st: loop to insert underscore before year suffix

[Nick Cox <njcoxstata@gmail.com>]

Tacitly you are using Stata 12 and so could use -rename- directly,  
without needing any programming. Alternatively, -findit renvars-.

All that said, underscores are not needed here. See my FAQ on - 
reshape- for how to extract stubs using -unab-.
