**
** PURPOSE: This sample program demonstrates stored procedures.
**
** There are two parts to this program:
** - the inpcli executable (placed on the client)
** - the inpsrv library (placed on the server)
**
** The inpcli routine will fill in an input SQLDA with 3
** entries. The entries are the names of presidents. The
** inpcli routine will also place the value "Presidents" in
** the io-data variable. It will then call the sqlgproc
** API passing it the input SQLDA and the io-data
** variable.
**
** The sqlgproc API will call the inpsrv routine stored
** in the inpsrv library.
**
** The inpsrv routine will take the information received
** and create a table called "Presidents" in the "sample"
** database. It will then place the values it received in
** the input SQLDA into the "Presidents" table.
**
