C2010   Incorrect number of arguments

     Explanation:  You called a built-in CA-Clipper function with the
     wrong number of arguments.  Unlike calls to user-defined functions or
     non-built-in functions, the CA-Clipper compiler performs argument
     checking on built-in functions.  Refer to the "Reserved Word" appendix
     in this guide for a complete list of predefined functions.

     Action:  Correct the call to the built-in function with the correct
     number of arguments and recompile.  The correct syntax for all functions
     can be found in the "Language Reference" chapter of the Reference Guide.
