Jeff: There appears to be a bug in the way RAID (RAID.FAI[CSP,SYS] as of about 3/1/77) handles the symbolic printing of UUO's in the Non-Stanford version( It always prints them as a funny octal number). It appears to me that the piece of code under the IFE STANSW switch: TRZE PV,40 MOVE D2,TABUUO(PV) IONOT: should be moved back to immediately before the label OPWIN (page 40). Jim Low
