Re: st: converting numbers to strings

foreach n in 07 09 11 13 {
         replace abc`n' = myfunc( abc`n')

would work here. Also,

forval n = 7(2)13 {
      local n : di %0.2f `n'
      replace abc`n' = myfunc( abc`n')

When I say "would work", the presumption is that "myfunc" is replaced
by a legal function name.
