^COMMANDS TO <BACKUP ARE IN THE FORM OF VERBS. <BACKUP PROMPTS
WITH A "/", and has
THREE KINDS OF VERBS:
.skip 1
.indent 5
1.##^action
.skip 1
.indent 5
2.##^status setting
.skip 1
.indent 5
3.##^tape positioning.
.sk 1

.SKIP 1
 ^THE ACTION VERBS ARE:
.SK1
.TAB STOPS 24
. ;<SAVE SPEC-LIST	SAVE THE SPECIFIED DISK FILES ON TAPE
. ;<RESTORE SPEC-LIST	RESTORE THE SPECIFIED FILES FROM TAPE TO DISK
. ;<CHECK SPEC-LIST	VERIFY THAT THE DISK AND TAPE FILES AGREE
. ;<[N]PRINT SPEC	PRINT A DIRECTORY OF THE ENTIRE TAPE ON SPEC
.SKIP 1
^THE ACTION VERBS PERFORM <I/O AND OPERATE ON THE TAPE
SPECIFIED BY THE LAST <TAPE VERB (ONE OF THE STATUS SETTING VERBS).
^A TAPE MUST BE SPECIFIED BEFORE USING ANY OF THE ACTION COMMANDS.
.SKIP 1
^THE ACTION COMMANDS TAKE AS AN OPTIONAL ARGUMENT A LIST OF FILE
SPECIFICATIONS IN THE STANDARD FORMAT OF DEV:FILENAME.EXT[DIRECTORIES].
^THE FILE SPECIFICATIONS MAY HAVE WILD CARDS. ^THE USER MAY SPECIFY
BOTH AN INPUT AND AN OUTPUT SIDE (OUTPUT=INPUT) OR JUST THE INPUT
FILE SPEC. ^THIS ALLOWS FILES TO BE RENAMED AS THEY ARE SAVED OR
RESTORED. ^FILE SPEC ENTRIES IN THE LIST ARE SEPARATED BY COMMAS.
.SKIP 1
^IF NO ARGUMENT IS SUPPLIED WITH AN ACTION COMMAND <BACKUP WILL
DEFAULT A FILE SPEC IN THE FOLLOWING WAY. ^THE DEFAULT FILE SPEC FOR THE
OPERATOR  IS <ALL:*.*[*,*,*,*,*,*]. ^THIS SPECIFIES
ALL FILES ON ALL ^^UFD\\S AND ALL ^^SFD\\S OF ALL FILE STRUCTURES WITH
NO RENAMING.
.SKIP 1
^FOR A USER NOT LOGGED IN UNDER [1,2] THE DEFAULT FOR THE <SAVE VERB
IS <DSK:*.*[<PPN,*,*,*,*,*]. ^FOR A USER DOING A <RESTORE, THE DEFAULT IS TO TRANSFER THE USER'S FILES ON TAPE TO THE USER'S DISK
AREA; SO THE DEFAULT SPEC IS <DSK:*.*[<PPN,*,*,*,*,*] = <ALL:*.*[<PPN,*,*,*,*,*]. ^THE <CHECK VERB DEFAULT IS THE SAME AS THAT FOR <RESTORE.
.SKIP 1
^THE ARGUMENT FOR THE <PRINT VERB IS A SINGLE FILE SPEC.
^IT'S DEFAULT IS <LPT:BACKUP.LOG.
.SKIP 1
^NOTE THAT SPECIFYING ANY OF THE FILE SPEC FIELDS OVERLAYS ONLY
THAT FIELD AND LEAVES THE REST OF THE SPEC DEFAULTS WITHSTANDING.
^UNDER NO CIRCUMSTANCES DO THE FILE SPEC FIELDS BECOME "STICKY"
PARAMETERS, E.G. SPECIFYING THE <PPN FOR ONE SPEC DOES
<NOT CARRY OVER TO THE NEXT SPEC IN THE LIST.

.SK2
^THE STATUS SETTING COMMANDS SET A PARAMETER
WHICH AFFECTS FUTURE ACTION COMMANDS. ^ONCE A STATUS PARAMETER IS SET,
 IT REMAINS IN EFFECT UNTIL CHANGED BY THE USER. ^THE FORMAT FOR
DATE/TIME ARGUMENTS IS <DD-MMM-YY:HH:MM:SS. ^THE STATUS SETTING
