[Equest-users] Blind controls in eQuest/ DOE2

[Carol Gardner]

Hi Shuichi,

I have not actively used this area of eQUEST, but I can pretty much
guarantee that there will not be a schedule ever in eQUEST that is just
called "SCHEDULE". The reason for that is that there are just too many
schedules in eQUEST for any one of them to claim the glorified name of
"SCHEDULE". That coupled with the fact that schedules are also, of
necessity, split into DAY-SCHEDULE, WEEK-SCHEDULE, AND ANNUAL-SCHEDULE, you
can see that when you find yourself typing simply "SCHEDULE" after your
command an alarm should go off in your head that says something like "Oh,
oh, I'm putting some nonsense into eQUEST that may cause the program to go
off in some sort of GI/GO loop, I guess I'd better research the topic a bit
more."

You sound like a user of some experience so I will just encourage you to dig
a little deeper, keeping in mind the schedule structure in eQUEST and the
use of the Building Description Language.

Cheers,

Carol
