I scanned the file and noticed the positions had up to two digits. But I also used Integer_IO's Get, so I don't think it mattered.

I was wondering if there was a pattern matching library I could use, and had wanted to ask that, but forgot.

GPS, and learning about it as I go, which unfortunately is a bit odd on MacOS Catalina. It has some strange behaviors (e.g., dialogs pop up as full screen tabs), and since AdaCore won't support GPS on MacOS anymore, I should look at something else. I like IntelliJ's Idea a lot, but my vague recollection is that its Ada plugins are primitive.

May I ask what you mean by, "Reduce in the sled rental count"? I'm starting to wonder if we're talking about puzzles from different years.
