Translating from BS2 to BS1 coding styles

Hello!
I'm in the process of sorting out how to translate one of my BS2 programs who when running displays its thoughts on a Parallax display.
This is the fragment that needs solving:
The whole idea of initializing the variables that the program needs is what is confusing the stamp's tokenizing process.
And this is the full program that came from:
It is the framework for the whole Idea I started up with back a good many years after buying from RS an LCD display that Parallax had designed the daughterboard for it. When running the program passes data out to a connected programmable logic chip, and then displays its response. It works well enough on the BS2 device I have here, but I wanted to translate it to the recently arrived BS1 device.

And I'm inclined to agree. I remember your efforts regarding translating a BS2 program that would talk to a TI Calculator, to a BS1 version.
Naturally I tried out both versions. I found that the BS1 version ran faster as applied to the BS2 version.
I changed the flag from "unsolved" to "solved" simply because Duane's translation looks perfect both in here and on the IDE tools.
