I had thought that IEBCOPY invokes Binder under-the-covers, so
I'd expect very similar behavior.
It might. I don't know the internals.
* Both the Binder and IEBCOPY use the block size only to set the maximum
size of a text block to be written, and write shorter ones under some
conditons. All the other records are typically written in short blocks.
And I believe that Binder is one of very few IBM utilities that employs
track balancing, reblocking to exploit residual space in a track. I don't
believe that QSAM, for example, generally does this.
The Binder and IEBCOPY (COPYMOD) both use TRKBAL (whether directly or
indirectly ;-).
