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 .

Level 2 – PSW with product samples and limited supporting data. Level 3 – PSW with product samples and complete supporting data. Level 4 – PSW and other requirements as defined by the customer. Level 5 – PSW with product samples and complete supporting data available for review at the supplier's manufacturing location. Complete ...
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 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.
There are two storage fields assigned to each class of interruption on the S/360; an old PSW double-word and a new PSW double-word. 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.
