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"
  if `x'==a {
    use tempa, clear
            }
  if `x'!=a {
    use tempb, clear
            }
  qui: do stuff2
  di "Line 2"
}

r.
