If you are *not* specifying ARCH(nn) where 'nn' is the architecture level of

Byte addressing on the 1106 was direct, specified in the j field of the
instruction. Indirect addressing only used the right 22 bits of the indirect
address word. At least on the 1106 you had a choice of byte sizes.

Well, actually CDC until the bitter end. Cyber 180s, introduced in the

ECS is specific to catalogs and uses a structure for inter-image communication.
RLS uses a local address space (SMSVSAM) for local communication AND a

Both are performance related.

Ok, building parallel sysplex. For the catalogs I am planning on using ECS for

What is the recommended method for handling the catalogs in a parallel sysplex,

Some other things I have observed. Sequentially searching large arrays
