You mean like ZZZZZC0, ZZZZZC1, ZZZZZC2?  (CCL scratch files)

Gee, we used to do that for real during Systems Time on NOS.  Great fun
submitting a job which kills off IAF, does a SYSEDIT, and brings IAF back
up, all from a terminal at home.

The history mechanisms are a sorry excuse for a dayfile.  A dayfile,
however, can be heuristically treated like a history mechanism.
A custom Unix shell could make history LOOK more like a dayfile, but
it won't be quite as useful.

CDC eventually provided that feature on the DAYFILE command.

What I always wanted was an option so that the user could have the system
write ACCOUNT dayfile messages into the user dayfile, too.  Especially
if the site is recording permanent file activity in the ACCOUNT file.
