>V64COMMON=YES, It is quite apparent from the syntax diagram in the prolog of IARV64 that V64COMMON=YES may be specified only if you specify AFFINITY=SYSTEM. And the default is AFFINITY=LOCAL. Thus you in effect asked for AFFINITY=LOCAL,V64COMMON=YES.
The grouping and indentation syntax format historically used in macro-book syntax diagrams obviously leaves a lot to be desired. RR-track diagrams do, at least, show the appropriate relationships. Nevertheless, the wording of the book with respect to using V64COMMON is correct and not misleading. The description for V64COMMON=NO/YES begins with: "When AFFINITY=SYSTEM is specified". This is how the book indicates "use x when y" where "x" in this case is V64COMMON and "y" is AFFINITY=SYSTEM. Since you did not specify AFFINITY=SYSTEM (and since SYSTEM is not the default for AFFINITY=), you get a syntax error message. What is not clear is why you are specifying V64COMMON=YES (or AFFINITY=). Are you using shared-common? I'm not actually sure at all in what way AFFINITY applies to storage obtained by REQUEST=GETCOMMON. Maybe that's where the books led you astray. What is misleading is the description of the AFFINITY keyword. The description for AFFINITY could/should be significantly changed/improved. I don't even know what AFFINITY means in the context of a non-shared memory object. That is what is missing. Do you really need AFFINITY for V64COMMON? It seems unlikely. Yet the wording leads you to suspect. The description of AFFINITY includes -- Nonshared memory objects are affected only by AFFINITY LOCAL. -- 64-Bit Common memory objects are not affected by AFFINITY=LOCAL Perhaps the first should be -- Nonshared non-64-Bit Common memory objects are affected only by AFFINITY LOCAL. The "first" was added to the macro in z/OS R5 (which is prior to GETCOMMON). Perhaps they did not realize the contradiction when they added GETCOMMON in z/OS R10.
