However if you already have some word processing background then it is quite easy to learn If you are dissatisfied with your current system then ZORLOF pro bably has the things you need This system will appeal particular ly to anyone writing three or more pages who likes to have his pages numbered neatly and likes to avoid too many drafts Writing articles for magazines is easy but writing scientific articles is something which most word processors cannot manage They are defeated by the need for special characters and the superscript for reference is often awkward In both these areas ZORLOF is exceptionally good Anyone who is the secretary or treasurer of a club will be interested in the form letter facility Like many of the bet ter word processors the system can be used for BASIC and EDTASM program development as well ASCII word processing A few years ago WORDSTAR and LAZYWRITER were the benchmark for comparison of other word processors Now we may have a new comparison stan dard in ZORLOF THE ACCEL4 COMPILER A SOFTWARE REVIEW by Dayal Abeyasekere A BASIC Compiler for the TRS 80 Models II and IV Compilers translate programs writ ten in high level languages like BASIC and FORTRAN into machine language The resulting machine language programs usually run much faster than the high level language versions from which they are derived The most important disadvantage of compilers written for small mic

The bigger the number the slower the program will run The author recommends four aliens for optimum performance These aliens will pursue you and will also consume any dots they pass over lessening your possible score It appears that the only way to destroy dots on the edges of the screen is to attempt to manoeuvre the aliens over them If you go to the edge of the screen yourself you will get stuck When you have despaired of clearing the last of the dots hitting will give you a new screen CRICKET CoCo by N Cooper Cricket is for two players one is the bowler and one is the batsman The bowler uses the right and left arrow keys to line up his bowl and presses B to bowl When this has been done the batsman will appear He uses 1 to go left and 2 to go right The blue strokes that appear on the field are the fieldsmen If the ball hits one of the strokes the batsman is caught Sometimes when the batsman hits the ball the tone will sound for a hit but the computer may say that you are bowled This is because the batsman hits the ball and it gets an edge and goes onto the wicket If you run the program and the computer locks up then this is because your computer will not take the POKE statements in lines 100 940 and 950 You should delete the statements but the program will execute a lot Slower If your computer does take the statements and you BREAK the pro gram during execution the
