Hello DFSort experts!

Where can I find the explanation of SORTWK space usage? I seem to recall reading that only the primary space is used on a SORTWK, so if I have
//SORTWK  DD SPACE=(CYL,(5000,2000))...
I will only get the primary space of 5000 cylinders, and the other 14x2000 cylinders is never used. Is that right?

Is there a written explanation I can forward to the programmers so they understand this?

Also (since I know it will come), is there any good way to calculate how much DASD sortwork would be used? I know this depends on what is in memory at the time, but want to get a better handle on how Sort determines what it needs.

Thanks, everyone! This might be a good discussion!
