Hi Henry!

If what you want it is to know if all the one letters of a string exist in one another string? Try this:

Local llOk, lnFor
lOk = .T.
mCharacters = Alltrim(mCharacters)
For lnFor = 1 To Len(mCharacters)
   IF Not SubStr(mCharacters, lnFor, 1) $ "ABCDEFGHIJKLMNOPQRSTXYZ"
      mOldID = IncompleteList.ID
      llOk = .F.
   ENDIF
Next
If llOk
   mID = alltrim(SUBSTR(mOldID,3,7))
Endif

Bye!
