WebThe 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 code. WebNov 11, 2024 · Offset 274 in the load module is the start of a routine called $$PRTOUT, which somehow seems to relate to the PRINTOUT macro seen in the assembler source. So, register 15 is pointing at the entry point of routine $$PRTOUT. This indicates that register 15 has been loaded with the entry point address of routine $$PRTOUT. shoreton bungalow culbokie https://zigglezag.com
