What do you understand by the following terminologies?

Answer»
  1. AMODE(31)
  2. AMODE(24)
  3. RMODE(24)
  4. RMODE(ANY)

All 4 are the OPTIONS that are available in COMPILE or link editing. AMODE expands to ADDRESSING Mode. AMODE(31) and AMODE(24) REPRESENTS that the addressing mode used is 31-bit and 24-bit respectively. When we use AMODE(ANY), it indicates that either 31-bit mode or 24-bit addressing mode can be used and it is dependent on the value of RMODE.

RMODE represents Resident Mode within the virtual storage. RMODE(24) represents that the mode can reside within virtual storage below the 16 Meg line. RMODE(ANY) represents that the mode can reside below or above 16 Meg line and the ADDRESS bit can be either 24-bit or 31-bit depending on the RMODE.
