Thread: Addressing mode of current Mainframe environment

In COBOL we are having 2 types of addressing mode(24 bit or 31 bit) which can be specified in cmpile jcl PARM parameter. I am using CMANCOB2 or COBOL390 , how to identify which addressing mode it uses. What is the addressing mode that current Mainframe environment has?

NOTe : [This question was asked by suresh kumar]

The current z/OS operating system runs in 64 bit mode. In the past, any memory above the 24 bit limit was called "above the line". This now means between the 24 & 31 bit limits.
"Above the bar" is now used to specify any memory that is above the 31 bit address limitations.
