Program status word register

Length of PSW

The statement The program status word (PSW) is, typically, 32 bits in length. may be true for 16-bit processors but it is incorrect for 32-bit and 64-bit processors. For those 64 bits and 128 bits are more common. Shmuel (Seymour J.) Metz Username:Chatul (talk) 15:46, 16 November 2010 (UTC)[reply]

PSW layouts

@Guy Harris and Tom94022:I've copied the PSW tables from IBM System/370 and added the standard S/360 and 360/67 formats. The way those are laid out looks OK for 64-bit registers but would be too crowded for 128. I've used a different format for z/Architecture, and have a prototype at User:Chatul/sandbox/PSW; it needs some tweaking to separate words more clearly. Once that's ready to include in the PSW article, should I change the existing tables to the same style? Shmuel (Seymour J.) Metz Username:Chatul (talk) 00:52, 28 December 2020 (UTC)[reply]
