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 four condition codes in the processor status word (PSW) are N indicating a negative value; Z indicating a zero (equal) condition; V indicating an overflow condition, and; C indicating a carry condition. Instructions in this group were what Digital called "micro-programmed": A single bit in the instruction word referenced a single condition ...
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.
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 ...
A simple trick allows to protect the "|" in template parameter values while still arriving as real "|" delimiter in the Wiki table, see the magic word {{!}}. Note that "!" (exclamation mark) has no problems with templates, it's the other delimiter used in Wiki tables. Here's the code for plan B: {|
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.

The PSI data as defined by ISO/IEC 13818-1 (MPEG-2 Part 1: Systems) includes four tables: PAT (Program Association Table) CAT (Conditional Access Table) PMT (Program Mapping Table) NIT (Network Information Table) The MPEG-2 specification does not specify the format of the CAT and NIT. PSI is carried in the form of a table structure.
