That doesn't explain why you'd want the directory to be allocated in full
tracks, though.

IIRC, I was taught that the entire track was formatted as directory blocks,
but you could only allocate/access the ones you asked for in JCL.

Regardless of how many you specified, the first member starts on/in the
next track after the directory.

That's not correct.  Never was.  You can prove it easily enough.  Create a
PDS with one track, no secondary. If what you say was true, you'd never be
able to create a member.

Tom,

I tested this in the old days of SLED DASD, and the directory was a keyed track and you COULD NOT store a member in the directory track. It always took 2 tracks minimum for a PDS (of course, this has not been true for about 15 years).
