Re: st: excluding variables by type

[Margaret R Grove <margaret.r.grove@Dartmouth.EDU>]

Hi,

Here's one method:

unab vlist: _all      /*  assign all variable names to local variable 
vlist  */
foreach x of varlist `vlisit' {
         capture confirm string variable `x'
   if _rc~=0 {
      /*  do numeric variable processing here */
   }
   else {
      /* do string processing here */
   }
}
