Passing Parameters


   The set of provided functions are used to obtain parameters being
   passed from your Clipper code.  When you use the __PAR functions,
   follow the pseudo sequence below:

   . Move the parameter number to be obtained into a register.

   . Push the register.

   . Call the appropriate __PAR function for the data type of the
     parameter.

   . The parameter is received in registers, either by value or by
     pointer.

   . Restore the stack.

   In addition, it is important to remember that Clipper is written in C
   and all parameters are passed as C data types.
