Extensions issue 1

Before we get too involved with making changes let’s provide a simple way to make backups of your master program (that is an empty basic program and machine code).

If you have more than one tape of PRO/FILE, you are aware of the problem of making improvements since they must be typed into each copy individually. To simplify this, follow these instructions (to use my SAVE routine described later you need to do this anyway so do it now).

The following is only for those who have added the TALLY routine from the manual AND the MACHINE CODE SORT routine from Tom Woods’ Breakthrough newsletter. When the mc sort is added to a program containing the tally function two bugs appear. The first and most important is that you can no longer do an…

The display menu and edit menu each consist of several sections. | prefer to see as many options at one time as possible. Also, if you have a long search command (more than one line long) you will run into a problem with the screen SCROLL. These changes solve both situations and save about 350…

Being a band director, I often made printouts of my students by instrument. First I would print all the flute players, then clarinets, etc. However, I always had SEARCH IS COMPLETE printed in between each section. Also, I use a number of codes in my files, so to help me keep track of their meaning…

At the end of line 5040 there is a delay loop in some versions which I have found to be unnecessary in my experience. You can simply delete the section.
