Goto case?

[Paul N]

If I'm within a switch, then saying "case 10:" creates a sort of
label. Is it possible to jump directly to one of these, eg "goto case
12;"? I realise this can be done by adding a "normal" label next to
the "case" label, and that it might be possible to arrange a similar
thing by cunning use of fall-through or by changing the variable and
executing the switch again, but is there a neat syntax to jump to one
of the other cases?

Thanks.
Paul.

A case expression is not a label (and in any case must be a
constant).
So there is no sort of label at all.

No.

Perhaps the "neat" way is to factor the common code out to a separate
function, and call that one from several locations.

Create a function to call from the case and call that function.

But there is the lovely code (Tom Duff's (May 7, 1984) method for fast
copying) which should be kept tidied away in a function and with a good
comment somewhere..
