Re: use of :: (Re: Setting background color)

I am thinking of re-defining "::", per Mike's example, at the start of
programs that will be compiled only with later versions of SF (i.e.,
2.2.2.9). Is this a good idea?

If so, I assume that I must also ensure that I am in the Forth vocabulary
when it is executed. Of course, this is generally true at the start of a
program with no other re-definitions of ":", but ...

Is there a more general purpose definition that ensures the correct
vocabulary (or other tricky stuff) or is the suggested code adequate for
this purpose?

Mike,

There is no reason I can think of not to define it thusly.
I actually believe, in hindsight, that all references to
api calls in SwiftForth should be preceeded by the ::
operator, as doing so would make the search order code
much simpler. If it were done this way, the :: would
look up and compile the reference to the next word.
However, legacy probably demands that this not be imposed
on the user community. Just my $0.02 .

Rick
