// File:    KO_PARAM.CPP
//
// Purpose: This file contains functions for implementing
//          parameterized queries. Since I have not shown
//          implementation of params in the sample, all the
//          functions r just placeholders. Params work
//          thru APD and IPD just like actual results
//          work thru ARD and IRD
//
// Exported functions:
//                       SQLBindParameter
//                       SQLDescribeParam
//                       SQLNumParams
//                       SQLParamData
//
