(*CATCH '(A B C) (COMPUTE)) in MacLisp means to catch throws to any one of
the tags A, B, C. If the Lispm supports this extension, it is broken in
system 27.6 on CADR-11. If not, then *CATCH should barf when given a
non-atomic first arg.
This is some random feature invented by GLS or JONL; the Lisp machine has
never claimed to have any such feature. Note that if you are throwing
out of (COMPUTE) then *CATCH is in fact never getting called (not that it
looks at its arguments anyway).
I suppose there is no complelling reason why the Lisp machine couldn't do this.
You could also implement it yourself easily enough with CATCH-ALL.
