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.

A normal part of the mortgage application process, conditional approval means the lender will give you a home loan, provided you address certain additional criteria.
The high-order byte of the instruction specifies the operation. Bits 9 through 15 are the op-code, and bit 8 is the value of the condition code calculation which results in the branch being taken. The low-order byte is a signed word offset relative to the current location of the program counter. This allows for forward and reverse branches in code.
The California Code of Regulations (CCR, Cal. Code Regs. ) is the codification of the general and permanent rules and regulations (sometimes called administrative law ) announced in the California Regulatory Notice Register by California state agencies under authority from primary legislation in the California Codes .
But as of Oct. 25, California had only collected $18 billion — a far cry from the $42 billion the state forecast back in June. Understandably, this news might make employees nervous.
