It is possible for all the methods listed in Methods available for specifying runtime options to be used for a given application. The order of precedence (from highest to lowest) between option specification methods is:
Options specified on invocation of the application:
If you select PLIXOPT or #pragma runopts(), specify it in one and only one compile unit in the application; for example, in the main routine. If multiple CEEUOPTs are present, binder input ordering determines which CEEUOPT is used in an executable program. Only the first CEEUOPT CSECT linked in an executable program is applied. The binder treats any subsequent CEEUOPTs seen in the input as duplicates and they will be ignored.
When the non-overrideable (NONOVR) attribute is specified for a runtime option, all methods of specifying that runtime option with higher precedence are ignored.
