Have made a symbol 'go or `nogo and want to use an unless condition that only
executes some commands for the 'go condition. How should the unless condition
be constructed with the `nogo?
(defconst modust-statck 'go)
(unless modust-statck

Yes. Doesn't that do what you ask?
On the other hand, `defconst' is specifically
intended to give the message to human readers
that neither humans nor code are expected to
change the value of the variable. It's a
proclamation to human readers that the var is
really a constant.
And if it's really a constant, then why test
it (e.g. with `unless')? Either you should
use `defvar' or you just do XYZ instead of
(unless modust-statck XYZ). No?

You are right. Would work better if I can pass 'go or 'nogo to a function. I would still
need the "(unless param". With some "eq" declaration for 'nogo.
