Actually, all this got started when someone said they wanted to make a
table program in asm.  They wanted a routine that evaluted an equ variable
(y0,y1,y2...)

But it looks like I'll have some free time over the weekend.  So I might
get started on the ROM Browser.  I was just kind of brain storming on how
it would be.  Once it's written I'll mess around with it to see what it
needs to make it a good tool.
