*& + This program demonstrates how easy it is to convert Smartforms to
*& and save as local file
*& + This example also demostrates how to skip the PRINT PREVIEW screen
*& where we give the default printer name. The name is set in the program.
*&
*& NOTE: The smartform called here is an example with no relation to the
*& standard forms. You will have to do the Smartform data population
*& befoer you use the code for PDF Conversion. Data can be sent to the
*& smartform through the Function Module G_FM_NAME's EXPORTING or
*& TABLES section
