C2022   Redefinition of predefined function

     Explanation:  You declared a function with the same name as a
     predefined CA-Clipper function.  Unlike ordinary CA-Clipper functions,
     predefined function names are reserved and cannot be redefined.  Refer
     to the "Reserved Word" appendix in this guide for a complete list of
     predefined functions.

     Action:  Rename your function or procedure to resolve the conflict
     and recompile.
