Is there any reason to have 64-bit COBOL on z/OS ?
Of course except satisfaction when watching AMODE 64 in ISPF member list...

Perhaps not in a homogeneous programming world in which COBOL is your only programming language. But, don't you need 64-bit support to be able to share data with other programs, written in other languages, that leverage 64-bit support? I'm thinking about parameter lists, addresses of in-storage tables, etc. Also, doesn't the run-time (LE) have some all-or-nothing restrictions on the addressing mode of the programs it supports within an address space?
