Mike was once more extolling the virtues of his latest discovery. He was dying to get me hooked on it. Thus far, I had managed to escape this latest language for the TRS-80, but I couldn't help being drawn to the keyboard every time I heard him chortle or gloat over another feature of his new toy. Finally I decided to take the fatal...

Info

TO TEST Program continues Both TIMES and CMD are Level III or DOS (disk operating system) commands, so called because, although Level II acknowledges them (with an L3 ERROR message), they have been reserved for system software expansion. What that means is that there is a memory patch point for each of them. In normal Level II BASIC, that patch point command effectively is jump to the L3 ERROR message. We change that in this program see lines 190 to 230 by patching into TIMES...

Read Q Sa Sqsassas

This would have read three sets of question and answer words, or we could have read all six sets in one operation. As it is, we chose to read just one question and one answer in line 70, and in line 80 we print the question word. Since Q is assigned to LION in line 70, that's what comes up on the video screen. We don't ask for the answer word A to be printed, so it isn't. At line 90 you're asked to input your answer, and line 100 then compares your answer with one, PRIDE, which has been taken...

Application

An efficient application for single drive, limited memory disk systems. When I had finally saved up enough money for a disk drive for my TRS-80, I only had 16K of RAM. Radio Shack says in the manual that you can operate TRSDOS with 16K, but when you load BASIC it turns out you've only got about 6K. That's not much for a program. Worse, TRSDOS and its friends and relatives do a darn good job of filling up the disk sitting in that lonely drive. Well, here is one application I found that requires...
