I discovered a glaring error in a PowerPoint tutorial on the use of the ED and EDMK instructions ... a presentation that I may have posted years ago. Included therein was a flowchart showing the conceptual operation of the instructions.
Recently, I coded an emulation of the instructions – following the guidelines of that flowchart – which failed miserably, alerting me to the errors in the tutorial. I have corrected the flowchart and slightly tweaked the presentation, an updated version of which may be found on my Google drive: https://docs.google.com/presentation/d/1ZEC6985JIzJZ5oNbinYNDefLzBpzctKD/edit?usp=sharing&ouid=104012833061983447284&rtpof=true&sd=true Apologies to anyone I may have confused with the earlier material.
