Chris could also use -ds- to filter his varlist to string variables only if that is a concern -- but that wasn't a part of the question.
Further, Daniel's example has an error - it should read:
*****
foreach varname of varlist v* {
cap conf str v `varname' //fixed
if _rc continue
if `varname'[5]=="#ERROR" drop `varname'
}
