Carl, I'm reading the fascinating BX.TXT. I have a question: why does this work: XPLeNCODE v2.0 b-gin [UNTITLED] [BX_]{<}PR|Enter a 2-char func mnemonic{>}pfun {<}RK{>}{<}RK{ >}[Q2_];*; -nd XPLeNCODEI don't understand where the recorded keystrokes go. I think it has to do with "PR|" which is undocumented as far as I can see.Thanks, Harry Harry Binswanger hb@xxxxxxxx
