Answer / rama krishna m.
Amode means Addressing Mode : by seeing the addressing mode we came to know whether system is running under 24-Bit or 31-Bit or 64-Bit Addressing Mode, if the os below O/S 370 then it is run under 24-Bit(it is uses 16 MB of Virtual Memory to run user program)this is called Below the line. From MVS/OS 370-XA(Extended Architecture)it supports 31-bit Architecture the Address Space is 2 GB. Then MVS/ESA supports more than 2 GB of virtual memory to run user programs. Z/OS only having the 64-Bit Architecture. ( if u want to see Amode then submit ur Cobol program thru Jcl, goto spool open Sysprint and have look for AMODE.
Rmode : Where the program is running ( Residency Mode )
