Just above the SR instruction, insert PRINT GEN, beginning in column 10, which will expand Macro code.

I believe you'll find that XREAD is an In-House Macro.

I vaguely recall ASSIST used an XREAD macro so it might not be in-house.

Robert,

Yes, I believe you're correct (CRS aside).

Many years since I've seen it or had anyone ask about it....

Bill, ASSIST is still around and I think U. Waterloo made it free a while back so it's probably still a viable way to learn Assembler.
