These GOTOs in the Basic programs is one of hardest things
for translation the old Basic programs into Euphoria.

Programmer needs to rethink all Basic goto algorithms in
terms of procedures, functions, Euphoria loops etc.
There is no another way.

But if that rethinking is done, Euphoria program shines!

Rob keeps Euphoria without goto to avoid the simple
replaceing of Basic crazy gotos by Euphoria crazy gotos.

*Any* Euphoria program must shine, I do understand Rob.
Euphoria is a new excellent high-level language for the
modern and perspective End User. Goto operator is good
simetimes for complicated low-level languages.

I have some little experince about translation Basic to Euphoria.
Why not to keep the almost Basic's syntax for such the library?

Say,

global function VAL(sequence s)
  --  real code
end function

Then Basic user can just write almost Basic program
in Euphoria.

I'm working on Basic/Euphoria DRAW procedure now
and it is almost ready.
Works for me on all SVGA Euphoria DOS32 modes.
I'll submit it when it's ready.
Rob has this my DRAW lib for testing with 2.5.

Good Luck!
