The AUR says "Of the 818 commands, 808 are shown by CAT." (page I-1). The ones not in CAT are tagged with a "-" in the "H" column of Appendix I. Those commands are: *H, *W, CLUSR, GRAPH, GREY, LAST, LIMIT, SigmaX^2, SigmaX*Y, and SigmaY^2. All of these are aliases for other commands which are in CAT, except for GREY, which must be typed in.
