Dear List,

I am trying to write a 'foreach x of varlist ...' loop in which I want
to use different data sets depending on which variable in varlist is
being processed.  When run, the following program correctly outputs
"Line 1" but fails to load tempa.dta and I cannot figure out why.  Any
tips will be most helpful.  Thanks.

foreach x of varlist a b c {
 if `x'==a {
   use tempa, clear
           }
 if `x'!=a {
   use tempb, clear
           }
 qui: do stuff
 di "Line 1"
