    STARSCRL

This program originally appeared in the October 1990 issue of Amstrad Computer
User as StarScroll Demo by Chris Wootton, which featured User Defined Graphics
(UDGs) for the Space Craft and Multicoloured (White & Grey) Pixels to
represent the stars and a simple through effective way to roll the screen to
push the starfield down.

The aim of this project is to recreate something similar in various compiler
languages under various Operating Systems, which has resulted in variations of
the program being produced.  

This particular version written using Small-C & FIOLIB for FutureOS, has 
created a version which uses an enhanced approach to moving the starfield, thus 
producing a smoother approach to the program. By setting up an appropriate 
array and moving those stars based on their positions, it appears as if the 
screen has moved, when it has not.
This Plotting routine in this version of FIOLIB has been rewritten by TFM to 
allow things like the Space Craft and Stars to be drawn and deleted based on
using black to overwrite around the areas, which has produced a good effect for
this Demo.

To Run this program in FutureOS, start '-RUNC.64K' first which loads the library
into memory. Then run 'STARSCRL.SMC' the Small C program.

In order to get out of this Demo you will need to reset the computer.
