I wasn't suggesting new device-dependent code for the old access
methods; I was suggesting a compatibility interface similar to that
used to allow you to open a DCB to a subsystem data set. Currently
OPEN has the ability to automatically acquire an ACB, open it and link
it to the DCB. I suspect that IBM could lift from VSE and OS/VS1 what
little code is needed beyond what is already there for SYSOUT.

That won't make them go away. They are an economic reality, and if IBM
wants to retain the customer base then it will need to provide for a
smooth migration.

No, the need is to preserve investment. The customer doesn't care
about "architecture"; he cares about fiscal issues, one of which is
the residual value of code that he has already spent a lot of money
one. Tell him that he must spend additional money to rewrite that code
and you have removed his incentive to stay with IBM.
Also, your statement has an implication contrary to fact. There was no
proposal to "move BPAM and BSAM"; there was a proposal to provide a
device-independent CI.

If you acknowledge that, then why do you oppose the CI that is
necessary in order to make it incremental?
