I have added one additional request to VSI. An option in the
"screen section" that simply disables all colour changing
commands from the compiler. Our default colours in the
terminal emulator are OK and do not need any changes.

Something like:

screen section.
01  scrPageHeader blank screen no-color-changes.
     02  value "Hello world - Screen section" line 2 column 1.

Or something similar...
