Contained within the PSW are the two bit condition code, representing zero, positive, negative, overflow, and similar flags of other architectures' status registers. Conditional branch instructions test this encoded as a four bit value, with each bit representing a test of one of the four condition code values, 2 3 + 2 2 + 2 1 + 2 0. (Since IBM ...
A status register, flag register, or condition code register (CCR) is a collection of status flag bits for a processor.Examples of such registers include FLAGS register in the x86 architecture, flags in the program status word (PSW) register in the IBM System/360 architecture through z/Architecture, and the application program status register (APSR) in the ARM Cortex-A architecture.
The processor stores the PSW, with an interruption code inserted, into the old PSW location and then loads the PSW from the new PSW location. This generally replaces the instruction address, thereby effecting a branch, and (optionally) sets and/or resets other fields within the PSW, thereby effecting a mode change.
The following computer algebra systems and software packages use some version of the Baillie–PSW primality test. Maple 's isprime function, [ 12 ] Mathematica 's PrimeQ function (that already uses 2020's version of Baillie–PSW), [ 13 ] PARI/GP 's isprime and ispseudoprime functions, [ 14 ] and SageMath 's is_pseudoprime function [ 15 ] all ...
PSW may refer to: PSW Science, the oldest scientific society in Washington, D.C. Personal Support Worker, Canada; PlayStation World, a UK magazine; Program status word, a control register in IBM mainframe computers; Baillie–PSW primality test in mathematics; Part Submission Warrant in production part approval process; Post Study Work Visa, UK
Personal support worker (PSW) is the title for a similar type of health worker in Canada. Personal support work is unique among health care professions in that the scope of a PSW's duties does not extend beyond what the client could do him/herself if the client were physically and cognitively able.

The instruction set does not contain conditional branch instructions. Instead, it contains conditional skip instructions which cause the following instruction to be ignored. A conditional skip followed by an unconditional branch performs a conditional branch. The skip instructions test any bit of any register.
Generally Accepted Accounting Principles (GAAP) [a] of Canada provided the framework of broad guidelines, conventions, rules and procedures of accounting.In early 2006, the AcSB decided to completely converge Canadian GAAP with international GAAP, i.e. International Financial Reporting Standards (IFRS), as set by the International Accounting Standards Board (IASB), for most entities that must ...
