    Using the Online Program Examples for RDO, RDML, and RDBPRE

   Online sample programs are available for use with the RDBPRE
   and RDML preprocessors and with Callable RDO. These programs
   are in the directory specified by the logical name RDM$DEMO.
   You can create an executable form (image) of any source program
   example for which your system has language support and then
   run the image to see how the program works. You can also create
   hardcopy listings of program sources and use them as references
   when you create your own applications.

   This file describes the RDBPRE, RDML, and Callable RDO sample
   programs.

   Online Program Examples

   The exact file names for the sample programs vary depending on
   the source language and the interface being used. File names
   containing the following strings are available:

   o  SAMPLE

      A program that performs numerous data manipulation opera-
      tions on the sample personnel database.

      Note that you can use the sample program C_SAMPLE.RC only
      with the RDO version of the MF_PERSONNEL database. For exam-
      ple, use the following command to create the database:

      $ @SQL$SAMPLE:PERSONNEL RDO M NOCDD

   o  CALL_OTHER

      A module called from the SAMPLE program that passes that
      program information for preprocessing and returns control to
      the SAMPLE program.

   o  ERROR

      A module that handles run-time errors for the SAMPLE pro-
      gram.

   o  DEPTFOR.FOR

      A program that performs several data manipulation operations
      on the PERSONNEL database.

   o  F_DDL_STMNT.FOR

                                                                  1

 















      A program that demonstrates how to perform data definition
      tasks from an RDBPRE FORTRAN program using Callable RDO.

   Table 1 lists the available programs with their supported lan-
   guages, and indicates the applicable interface.
