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 the Error Messages and Appendices guide
     for complete list of predefined functions.

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