Scheming with the Coco and Android

My dad used to say, “There’s the easy way, there’s the hard way, and then there’s Earl’s way that makes the hard way look easy.” I patched my input driver to replace “E” with ‘RUN”ED2’ in the input buffer. ED2 just says EXEC&H7C00. Hey, it works. lol.

I tried to squeeze the last line out of a bit of code that was rarely used. It didn’t work. I did it as simply as I could. It worked. While I was at it I saw that I had told my program that there were 26 alphanumeric chars instead of 36. Meant to be.

My latest problem was my fancy input driver which changed long names into pairs of characters changed hex numbers like &H7C00 into something like &AA. Boo. I fixed it in a way that fixed the output driver, too. Atta-boy Earl.

My program is designed for a 64k Coco 2. It runs in ROM mode and uses hi-ram and the top K of lo-ram for itself. At present, once you run it, it returns to Direct mode. Now all characters in names are significant. SAM=5:SAUL=6:?SAM returns 5. My next step is to integrate the editor.

Lines going up from the cursor now are shown in their crunched version. Going down they are shown in their uncrunched version.

I was using urbane for the disk io in my machine language editor, and I decided that it was overkill, so i wrote light (light urbane). Labels are all lower case, have to end lines, and variable names stay the same. That way you can have meaningful variable names that don’t change. Usage is light […]

My copy of urbane wouldn’t work so I figured that it just got corrupted. So I went back to the forum to get the original version, […]
