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.
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 ...
The Program Status Word (PSW) [2]: 71–72 contains a variety of controls for the currently operating program. The 64-bit PSW describes (among other things) the address of the current instruction being executed, condition code and interrupt masks.
Conditional move instructions write the contents of one register over another only if the predicate's value is true, whereas conditional select instructions choose which of two registers has its contents written to a third based on the predicate's value. A more generalized and capable form is full predication. Full predication has a set of ...

While postal codes are also used for sorting, they allow extensive regional sorting. In addition, several provinces have postal codes that begin with different letters. The codes replaced the inconsistent traditional system used by Canadians until the 1990s. Apart from the postal abbreviations, there are no officially designated traditional (or ...

A LCA petition approved by the United States Department of Labor must be submitted as part of the Form I-129 (Petition for a Nonimmigrant Worker) application for work authorization for H-1B, H-1B1, or E-3 status. [2] This is true both for people applying for their first H-1B work authorization and for people transferring to a different job.
