[Info-vax] Definition and use of AQB$L_LINK

[Jur van der Burg]

This field is used to link multiple AQB's together via a single linked list.
ioc$gl_aqblist is the global list pointing to all aqb's in the system. Each
acp has at least one aqb, and when an acp starts it it will normally link
itself into this list.

Why do you want to know this? Maybe we can get a better answer if we
have more details.

If you're interested, LD V9.3 has an acp which uses aqb's. The sources
are included in the kit.
