Date: Thursday, 10 November 1983, 23:16-EST From: Carl Hewitt <HEWITT at MIT-OZ> In ZWEI in Release 5.0 [GC'd Beta Test rev 3], dusty plum, on Lisp Machine Apiary-7 (3600): Meta-X copy file failed to copy a file from OZ to a LMFS because ESTIMATED-LENGTH is not a kown OPEN option. The LMFS must have been running on a Rel 4.5 system, right?
