I couldn’t wait to try it out. I carefully replaced all the stores with subroutine calls and cleaned it up a little. When I first tried it afterwards it didn’t work. I opened the editor and started looking around in the file. Then I noticed the save icon was red. I had forgotten to save the file before assembling and loading it. I saved it, assembled it and loaded it. Lo and behold it worked with no further changes. Now I’ll never be able to get to sleep. Oh well. It was worth it.
