Re: [colorforth] arrays in source

[Mark Slicker <maslicke@xxxxxxxxxxx>]

Another thought on this idea.

colorForth source is already an array. A function of the editor might be
to format sequences of numbers occuring in source as described in my
message below, rather than as a sequence of tagged numbers or large numbers.

A macro could then compile the source address, and advance the interpreter
past the array.
