C1001   Return statement with no value in function

     Explanation:  You specified a RETURN statement with no return value
     within a function definition.  In CA-Clipper, all function definitions
     should return a value even though the return value may not be used in
     the calling routine.  If you specify a RETURN statement without a return
     value, the compiler generates NIL as the default.

     Action:  Change the declaration from FUNCTION to PROCEDURE, or add
     the missing return value to the erroneous RETURN statement.
