do you think there could be a much easier way to do what i want to do? how
does the FORTH interpreter itself reckognize carriage returns as well as
spaces?

hmm... well i just realized, that i could probably make it work better by
integrating the important bits of VARIABLE *into* the routine. too bad i'm
using a trial version of SwiftForth, which lacks the source for the kernel,
otherwise i'd do it. anyway that solution worked, again except for lists
with CR's... : /
