Generates the SQL-INIT-FLAG variable for DB2 for OS/390 compatibility. The flag is updated when the SQL environment is initialized.
                  If you define this variable in your application, compile your application with this directive set to NOGEN-INIT-FLAG and the
                  variable will not be generated by the precompiler.
