The DCB has different layouts for different DSORGs;
hence the reason that it is required. If you clear
the DSORG before OPEN, there may not be sufficient
information for OPEN to work with. (I didn't try this.)

You could simply code the DCB with DSORG, and at run-time, reinitialize
the DSORG field. Why would you want to hand-craft a control block?

Just to be a bit pedantic, he could build his own DCB without using the
macro. In the past I've committed a few programs that build their own
control blocks, e.g., DCB/DEB/IOB combinations. Would be interesting to
try this without a DSORG.
