We had a set of networked TRS-80 Model 3s in high school, and used CLOAD for them. Everyone would type CLOAD and then I think the teacher did a CSAVE. This was Network 2 or whatever it was called in the Radio Shack catalogs, I suppose. It was available for the TRS-80s and the CoCos. That was the only time I saw it in the wild.

That’s an interesting thought. I need to read through the DLOAD to understand it a bit more, and then maybe see what the protocol was on the C64s. That might very well be it. Thus, why there is no DIR — it returns the directory as if it’s a BASIC program called “$” that you load and LIST. Interesting. Very DLOAD-like!
