    Sorry the information file with last months (August) GFA section  was 
 short  and cryptic,  there wasn`t much disk space left and I thought  it 
 more  sensible  to use it for the programs.   This is  probably  just  a 
 slightly extended repeat of what I said last month,  but here goes  with 
 the information concerning August`s GFA files:

 3-D Dister
 ==========
    I`ve  re-written  the replay so it runs 'flicker free' on  a  machine 
 without  a blitter.   I`ve also optimised the 352044 pixel record  by  a 
 WHOLE MINUTE by pre-calculating the trig. table.
    I still don`t think it runs on a half megabyte - WILL SOMEBODY PLEASE 
 LET ME KNOW!!  [Note the 2-D dister was on July Ictari disk.]

 Infinite Sprites
 ================
    Nothing much new to say, I`ve simply converted it to GFA 2, [note the 
 GFA 3 version was on July Ictari disk.]

 Rasters, Rasters, Rasters
 =========================
    I`m afraid I went raster mad!  Firstly, BORDER.LST should explain the 
 basic theory of my "pseudo rasters".
    Animated routines include:  bouncing RAST_BAR, simultaneous BI_DIRECT 
 rasters  and simult.  BI_BARS (GFA 3 only).   Finally a crappy  13_COLOR 
 "pseudo interlace" thingy using rasters.

 Star-Field
 ==========  
    This was a quicky based on a little theory of fixed,  2-D, concentric 
 circles,  so don`t expect too much from it!   I know there are dozens of 
 other star routines around, smoother and more efficient!
