As I understand it, at least all debugging information (TEST option) is now 
added as deferred data classes in the program object instead of being sent to a 
separate dataset at compile time.

The COBOL Pgmr's Guide says to totally eliminate TEST data use NOTEST(NODWARF). 
 Not sure if that eliminates all deferred classes though.

Can you suggest why, and what for, does Ent. COBOL V5.1 for z/OS generate 
deferred data class(es) at all?
Is this being controlled by some compiler option that can be negated?
Obviously, Ent. COBOL V4.2 for z/OS does not do this.
