Letters to Technical Analysis

Dear Jack: I enjoy the publication very much. Please find enclosed renewal. I look forward to articles on Maximum Entropy. Please include a program on this that will run on Compu-Trac, if possible. Would you also consider an article and a program on equivolume charting? Your programs on the disk run very well and are very useful. Please let me know how I can modify TRIX #40 (STUDY.40) so it will run without user inputs so I can use it in procedures. I want to put the inputs right into the program. Thanks for the help, D.D.H. Redwood Falls, MN Dear D.D.H., The Maximum Entropy computer program (actually two sub-routines) will run within the Compu-Trac system. This will not be very user friendly because of Compu-Trac graphic, variable and memory constraints. The program will be about as much work to run and interpret as our Fourier spectrum analysis routine. The easiest way to get Compu-Trac compatable subroutines is to order our year end Volume 1 disk (Apple II+ or IIe only). Our published routines try not to rely on Compu-Trac unique BASIC commands. To use our subroutines in a Compu-Trac automatic procedure (i.e. unattended) all input must be through the use of a Compu-Trac GOSUB 100. This routine does more than just get input, it also stores and/or retrieves keystrokes from a text string Generally this means all you have to do is replace our input routine (GOSUB 1165 in this case) with GOSUB 100. Please send us a little information about your 'equivolume' charting, the term is not synonymous with just one technique. The Editor
