Delphi Support dBase syntax in MDX's

I was suprised (but it acutally makes sense) to find that delphi
fully supports old dbase syntax in index structures.  Therefore
indexes like str(Tnum,5,2)+dtos(mdate) + left(custname,5) work!
Simply enter the string in any dbase editor or even in the dbase
utility borland provides with delphi. No doubt BDE adds this for
compatibility, but I never found it documented anywhere.
