1 BRUSHELL This is an interface to the VAX DECUS program BRUREAD of Adrian Weiler. It is designed to load BRU sets created on the 11/73 A/D system onto the VAX. The program mounts MTA0: as the tape device. If study sets are being loaded in EMGWORK:[SYSTEMEMG] then the default protection bits are set to WORLD:READ,DELETE otherwise the default protection bits are modified to include OWNER:DELETE. In either case at process completion time, the original default protection is restored. FORMAT: $BRUSHELL/SELECT=.../DIRECTORY=.../NOMOUNT/NODISMOUNT 2 Command_qualfiers /DIRECTORY /DIRECTORY The [sub]directory name may be given with or without the "[" and "]" punctuation marks.I either case the system determines the remainder of the directory context. The presence of the punctuation mark ":" defines a complete directory definition. In this situation, no directory search is made and will be used directly as entered by the user. A study set WILL NOT BE LOADED IN EMGWORK:[SYSTEMEMG] (the pool) if it currently exists or has been processed in the past. To circumvent this, load the study set directly into a user work area. /SELECT /SELECT A numeric value[list]. A relative number which tells which study set to select from the tape. If the tape contains the following BRU sets then the option /SELECT=(2,5,6) will load study_sets SUB1234.BCK, SUB1237.BCK, and SUB0192.BCK. BRUSHELL defaults to the NEXT Bru set if SELECT is not specified. SUB1233.BCK (tape contents) SUB1234.BCK SUB1235.BCK SUB1236.BCK SUB1237.BCK SUB0192.BCK This is a required field. The user will be prompted for the SELECT values if the qualifier is not given on the command line. /NODISMOUNT /NODISMOUNT Since the DIRECTORY qualifier applies to one account, the BRUSHELL program is allowed to exit without dismounting the tape drive. It is expected to be rerun immediately with a NOMOUNT qualifier. A new SELECT qualifier will refer ot only those study sets yet to be loaded. Suppose we need to load SUB1235.BCK into EMGWORK:[HOWARDEMG] and study set SUB0192.BCK into EMGWORK:[JOHNEMG] from the tape contents shown below, then the BRUSHELL commands would be: $BRUSHELL/SELECT=2/DIR=EMGWORK:[HOWARDEMG]/NODISMOUNT $BRUSHELL/SELECT=3/DIR=EMGWORK:[JOHNEMG]/NOMOUNT BRULAB.BCK (tape contents) SUB1234.BCK SUB1235.BCK SUB1236.BCK SUB1237.BCK SUB0192.BCK /NOMOUNT /NOMOUNT Since the DIRECTORY qualifier applies to one account, the BRUSHELL program is allowed to exit without dismounting the tape drive. It is expected to be rerun immediately with a NOMOUNT qualifier. A new SELECT qualifier will refer ot only those study sets yet to be loaded. Suppose we need to load SUB1235.BCK into EMGWORK:[HOWARDEMG] and study set SUB0192.BCK into EMGWORK:[JOHNEMG] from the tape contents shown below, then the BRUSHELL commands would be: $BRUSHELL/SELECT=2/DIR=EMGWORK:[HOWARDEMG]/NODISMOUNT $BRUSHELL/SELECT=3/DIR=EMGWORK:[JOHNEMG]/NOMOUNT SUB1234.BCK (tape contents) SUB1235.BCK SUB1236.BCK SUB1237.BCK SUB0192.BCK 2 Examples $BRUSHELL/SEL=(1,3,4) (select the 1st, 3rd and 4th study sets FROM THE CURRENT TAPE POSITION into the current directory). $BRUSHELL/SEL=3/DIR=EMGWORK:[JOHNEMG] $BRUSHELL/SEL=(4,5)/DIR=EMGWORK:[JOHNEMG]/NODISMOUNT $BRUSHELL/SELECT=1/NOMOUNT/DIR=EMGWORK:[HENRYEMG]
