** The program will be compiled using the -x option which will
** use an external configuration file (ocs.cfg) based on the
** name of the application. The name of the application is
** defined at the time of INITIALIZING the application. Note that
** this is a new 11.x feature too.

Precompiler option to set in the makefile: cpre
-x.
The following is a sample configuration file for the preceding program:
[DEFAULT]
;
[TEST1]
;This is name of the application set by INITIALIZE_APPLICATION. ;Therefore this
is the section that will be referred to a runtime.
CS_OPT_ANSINULL=CS_FALSE
;The above option will enable comparisons of nulls in the NON-ANSI
;style.
