14. e form the original version of the BASIC Compiler took as designed and implemented by John Kemeny Thomas Kurtz and under their direction by many computer programming graduate students is a very interesting story to behold bet the computer room there at Dartmouth College was a flurry of activity as each graduate student that participated in the development and implementation of the BASIC Language compiler discovered and created many new ways to implement much needed commands by the student population at large After reading the book found a copy of the assembler source code as well as a BASIC User s Manual of one of those very first versions of the original BASIC Compiler that ran on that GE computer and must say it reminds me a lot of 6809 Assembler Source Code One of those implemented commands added later on during the development of their BASIC compiler is the MAT command Behind that simple sounding three letter keyword was a massive programming effort culminating in one of the most powerful features of the entire language With one single command one could affect changes to entire arrays of data or make calculations on a mountain of data all at once to sucha scale that it boggled the mind to think about it much less to fully understand how it did it My mind went round and round as studied examples of its use as had only heard of it but never had an opportunity to use it since the BASIC interpreters had ava
