Re: [colorforth] Octal in ColorForth for Music Notation? (fwd)

[Robert Patten <pattenre@xxxxxxxxxxx>]

I would us hex for packing notes into cells and ignore the extra bit or
define 16 notes or use the bit for half or full note.   Until ColorForth is
written in ColorForth, adding these things is very hard.   I do have words
that will display colorforth source,  but are not fully tested . Leading
zeros are not suppressed in  hex numbers.
