Hello. The link information in the 24-bit addressing mode consists of the instruction-length code (ILC), the condition code (CC), the program-mask bits, and the rightmost 24 bits of the updated instruction address.
I have never given much thought to the high byte when using this instruction and switched to BASR and BAS years ago. Just for personal interest, does anyone recall a program using the contents of the link register other than as a return address? Thanks for any replies.
