I have SwiftForth and SwiftX for the 68K family. Right now I've a
manufacturing test program for board-level diagnostics that runs on the
target under the PC host control with (for all practical purposts)
>print test. Test results appear on the PC printer (after a dialog for
printing that Windows does automatically). If the tests work out, the
target programs itself with the assembly-level tests. It works really
well except that the technician can't see anything happening on the
display for about 30 seconds and it really bugs them.

To solve all of this I think I need an output personality the combines
both the winprint personality with that for the screen. Specifically I
think I need to patch these vectors in winprint: [emit], pr-type and
[crlf]. I have these in SwiftForth and the seem to correspond with
what's going on in SwiftX. Is it possible for me to create a new
personality in SwiftX that would >print+screen ? Can I do it in
SwiftForth and patch it into SwiftX?

Thanks for taking a look at this,

Noel
