Jim Hawkins Dartmouth+ BASIC Interpreter V 3.0 2022

Download the BASIC executable (for Windows console)
Copy the executable into a folder of your choice, preferably something like c:\bp or d:\bp There is NO formal installation sequence. It does not run dlls or put anything in the Windows registry
Right click on the dbasic2022C.exe and send it to your desktop and/or pin it to your task bar. The icon is very ordinary as it is for a console application.
For now, save all your programs in this folter. It IS possible to put them anywhere you want, but, intially this is the easiest and requires just a save <filename>. The .bas will be tacked on to load files, use old <filename>
When you click to run BASIC, it will open up a tiny, hard-to-read console window. Click on the upper left icon of the window, select the Font tab and set the font size to 24 or 28. Once set, it will always open using this setting.
Please read the PREFACE of the PDF manual carefully. It should help you get started. The commands or statement meaning are in the text.

BASIC DEMO PROGRAMS

Solves four simultaneous equations using matrices mat4d.bas

Nine demo tests for matrix functionality mattestall.bas

Three demo tests of user defined functions: Nesting functions, Multiple variable functions fnnestx.bas

Using user defined functions to find roots of quadratic equation by trial and error, varying 'x' and 3 constants: y = a1x²+a2x+a3 polyloop.bas

Fahrenheit to Celsius dual column table using single dimension array. f2ctable.bas

Three simultanious equation solutions using 3X3 Determinants. Two dimentional array used for row and column. det3d.bas
