First: $ help copy $ help backup $ help files under vms should be helpful as it nominally goes down to examples. < Distant memory time... As far as copying files to the tape, did you < initialize it prior to MOUNTing it? < $ INIT MSA0: TEST !TEST being the volume name assigned to the tape That is correct. < $ MOUNT MSA0: TEST !tape "mounts", and is given the logical name < "TEST". It's mount/foreign msa0: < $ COPY DUA0:[MYDIRECTORY]FILENAME.EXT TEST:FILENAME.EXT !file spec is < an example....... $backup/log/image DUA0: MSA0:test.bak/sav < < /FOREIGN, and use < "BACKUP". Yep! A tape from a PDP-11 would ahve to be mounted foreign as it's a non files-11 format. Allison
