Version 1.21 Changes

1. Added an option to the config screen to allow EXIT to CALLing program when
   the report writer is ended.
2. Removed the BEGIN statement that was being issued when the report writer
   was started.  This has been removed to allow for the EXIT option mentioned
   above.  If you find a BEGIN is necessary, set the global variable
   %PVRQ_DOBEGIN to 1 before starting the report writer.
3. When the report writer is initiated to print a specific report by setting
   the global variable %PVRQ_RUNREPORT$ to the name of the report to be run,
   you may now tell PVRQ to print the report to a specific Windows printer,
   Word/Wordpad, or the ProvideX viewer.  This allows reports to be run
   without the need for the operator to select a printer.  Before starting the
   report writer, set the new global variable %PVRQ_RUNPRINTER$ to the name of
   the printer desired.  To print to Word/Wordpad, set this to *WORDPAD.  To
   print to the ProvideX viewer, set this to *VIEWER.  To print to a Windows
   printer, set this to *WINPRT*;Printer name;options, or to the name of a
   ProvideX link file that points to *WINPRT*.  *WINPRT* MUST be used when
   printing reports to a Windows printer.  If the open to the printer fails,
   the operator will see a message that the printer cannot be opened, and they
   will then be allowed to select another printer.
4. The report title and the column titles may now be expressions.  These are
   identified by the first character being an equal (=) sign.
