Yes. My comment was to insure that you were not going to just mimic DECB.

I was very sad when I realized what a giant change in the CoCo World Urbane 
would have made if I or someone else had done it in the beginning.

The two character names and line numbers are a huge drawback, one that I did 
not realize until I was deep into Urbane coding.

I had the TSC FLEX Basic Preprocessor before I got my first CoCo 2.

So the Idea was available before the first CoCo. I can understand my 
failure, I cannot understand the failure of others.

A Compiler was my understanding what you were planning.

Another post suggested using the DECB interpreter as a starting point.

I was thinking about creating a DECB to Urbane translator doing this.

I wonder if the BASIC09 disassembly might be a starting point.
