[Ql-Users] Is there a bug in QPC or am I bonkers (again!)

Morning all, I'm doing a bit more work on the next exciting episode of QL Today's LibGen utility. I have spotted a huge pair of bugs in my code, viz: li_libfile equ $03 ... li_unavmove.l #$,ws_litem+li_libfile(a1) bra.s li_rdrw ... li_avail move.l
