Well, this is not quite the program logger I wanted to write, but my programming days are long past. Instead, I created an Excel spreadsheet that automatically creates line numbering. Changing a LBL variable will change the line accordingly. You can also leave a space between programs for easier reading. The spreadsheet allows for 100 lines of program (I can make it longer if needed, or just use a new page for larger programs.) Enter program commands in the "Command" column beginning with the LBL command.
Not sure if anyone will find it useful, but it was a good self-test on creating Excel functions to do this.
If the formatting of the line number isn't the same as in the graphic, let me know, and I'll fix it (or tell you how). Here's what it will look like.
