Forgive me, but I can't remember what a channel appendage is or is for.

Could you just give me a quick answer/idea.

I used to do CCW stuff but since ECKD, I've only done CCWs for tape (which is now not supported).

Regards,
Steve Thompson

On the program we are both working on, the use of format-1 CCWs is not needed. In the end, it's one linked together program that is loaded by a
// EXEC card, thus it is always loaded in 24bit.


    So, the only reason for using a format-1 CCW is so that the I/O
buffer can reside in 31-bit space?
