After a slight pause finally I was able to implement the SCROLL and BORDER statements in IntyBASIC , also path selection for libraries using a command-line argument.
Documentation was added to manual and also SCROLL.BAS to show how to use it. The libraries are slightly accelerated with DZ-Jay contributions and some parts of scrolling code were contributed by intvnut. Myself I've a hard time getting scroll upwards to work without flicker, but it now is fine.
Looking forward to a test in real hardware of scroll routines.
For the newcomers, IntyBASIC is an integer BASIC language cross-compiler for Intellivision that helps greatly to ease game writing.
The original IntyBASIC thread is here http://atariage.com/...basic-compiler/ but I had to start a new one because I cannot edit further the original.
Platforms supported: Wind*ws, Mac OS X (32/64 bits) and Linux.
Edit: Mar/03/2014. Now added IntyBASIC v0.6 with CONST statement, also corrects a bug in FOR STEP, and added sample for MOB use in SCROLL.BAS
