i tried -replace- to without success e.g.:

. replace injurytype=minimal if injurytype>=.
minimal not found
r(111);

or

. replace injurytype="minimal" if injurytype>=.
type mismatch
r(109);
 
i have also tried -encode- and -recode- without luck. further advice/help would be appreciated.

regards,
bw
