HP 41 Catalog implementation

[Garth Wilson]

XEQ+ is similar to what you want, in Angel's WarpCore module. However, in trying it just now to verify something to write here, I did just find a serious bug, the first bug I think I've ever found in the 41cx, which I need to tell him about. It apparently crashed and I thought I lost everything; but after pressing various button combinations which I thought were supposed to reset it, I did get it back, but a lot of my key assignments were gone, and a few new ones were there but I couldn't tell what they were, like that CATALOG was doing something else, and so was XEQ. When I figured this out, the solution of course was to turn off the USER keyboard. My programs and files were still there, and the time and date were still correct.
