DSCB DSECTs?
OK, now I know I've gone blind: I can't seem to find a DSECT for the various formats of DSCBs. It also seems the Data Areas manuals aren't published any more (I don't find them in the z/OS 1.11 MVS or DFSMS bookshelves).

Re: DSCB DSECTs?
The answer to this question was given a couple of weeks ago by Bob Shannon and it is in the IBM-MAIN archives, always a good place to search along with the Internet for technical info. Try doing an ISPF 3.14 against SYS1.MACLIB(*) and/or SYS1.MODGEN(*) for the character string DSCB. Yes, there will be lots of hits, but the correct macro will also be found, and it will have a lot more lines of text in it than any of the others displayed. Or look in SYS1.MODGEN(IECSDSL1).

Re: DSCB DSECTs?
OK, now that you mention DSCBs, let me ask the VTOC gurus a question about
FMT1/8 DS1LSTAR -
I want to confirm my reading of how the number of used tracks for a
dataset is calculated in the context of large and extended formats.
Here's some pseudo-code for how I think it is calculated:
used_tracks = DS1LSTAR.TT (the first two bytes of the TTR)
if (DS1STRP) {
used_tracks = (DS1TRBAL 16) + used_tracks; // two new high-order
bytes
} else if (DS1LARGE) {
used_tracks = (DS1TTTHI 16) + used_tracks; // one new high-order byte
}
This seems odd to me - am I understanding this correctly?
My other question has to do with PDS-Es. I've read that LSTAR can't be
used, but I notice that ISPF 3.4 has used% for PDS-Es.

Can't comment on the rest, but for classical data sets, the use
is either zero, when TT and R are zero (as for a PDS/E, HFS,
etc.), or TT+1 (e.g., an empty PDS with 1 directory block would
have TTR=01, and TT alone gives you an incorrect 0 when you
need 1.
