WindowScrollUp (x1, y1, x2, y2, num_chars)

[boriel]

I have created a beta version for you with a library for this. Please test it and tell me if it's ok for you.

You use it with:

Code:

#include <winscroll.bas>

WinScrollUp(row, col, witdth, height) : REM Scroll up a window at row, col

See the example program in examples/winscroll.bas

Download version 1.12.0 and tell me if it works:
