Hi Hugh,

You can define a field reference parameter pRef, and then

Switch pRef.$type
   Case kCharacter,kInteger,kNumber
      Do something
   Case kBoolean
      Do something else
   Case kDate,kDatetime,kTime
   Case kPicture,kList
      OK message debug {Unrecognised type.  [nam(pRef)]    [pRef.$type]}
End Switch
