Hi All,

I would like to program a loop in STATA to change the name a long list
of variables ending with "_" and a letter, like these:

ab1535_a
ab32343_b
ab089790_g
ab3434_t
...........

I want to change them into

ab1535
ab32343
ab089790
ab3434
...........

I can use
ds ab*_*
local oldname `r(varlist)'

for each foreach i of local oldname {
rename `i' ????
}

I don't know how to complete this loop, Is there a way to program this please?

Thanks a lot!

Kate
