My *features* includes a & b, but not c
How can I say :

#+ (and a b (not c))

(I cannot find anything in CLtL2)
Any help would be appreciated.

Like that.

Look at the ANSI spec, CLtL2 is slightly older.

See 2.4.8.17 and 24.1.2.

Many thanks for your amazingly fast help.
I get no joy with this (I'm using MCL 5.0).
At least I know it is meant to work, so will try to dissect.

I don't understand the question.  Did you not say it, just now?

Perhaps you should use the hyperspec instead.

Be aware that this will test the features :A :B :C, rather than
symbols in some other package.
