Creating Directories and Sub-file Directories Using CREDIR
Function
The CREDIR program creates directories and sub-file directories.
CREDIR creates sub-file directories (SFDs) on any specified
structures, and it automatically creates any necessary higher-level
directories. If you do not specify a structure, CREDIR creates the
SFD on every structure in your search list.
You can use CREDIR to create ersatz device directories. CREDIR allows
you to create directories on all structures associated with a
specified ersatz device. As it creates each directory, CREDIR tells
you the name of the unit and the protection code associated with the
directory.
Format
R CREDIR
Create directory: dev:[dir]/switch
where: dev:[dir] is the device name and the directory specification.
You can specify an ersatz device name. /switch can be any of
the switches listed below.
By default, CREDIR creates the directory on device DSK:. The system
assigns the default protection code defined by the system manager. If
no code was defined, <775> is the default.
You can use the following switches to modify the CREDIR program:
/ALLOCATE:nnnn Specifies the number of blocks allocated
for the SFD.
/ERNONE Prints an error message if there are no
files in the request.
/ERPROTECTION Prints an error message if the request
fails due to a protection code
violation.
/HELP:arg Prints the HELP text for the CREDIR
program. You can specify S as the
argument to get a list of the switches
to the program.
/IN:nnnn Specifies the logged-in quota.
/NAME:name Specifies a mnemonic name for the
directory.
/NOOPTION Suppresses processing of the defaults
from your SWITCH.INI file.
/OKNONE Does not print an error message if there
are no files that match a wildcard
specification.
/OKPROTECTION Does not print an error message if the
SFD cannot be accessed because of a file
protection violation.
/OPTION:name Uses any lines in your SWITCH.INI file
that are specified as CREDIR:name.
/OUT:nnnn Specifies the logged-out quota for the
SFD.
/PHYSICAL Specifies that the device name is
physical, and to ignore logical names.
/PROTECTION:nnn Gives the SFD the protection you specify
in nnn.
/RUN:file-spec Runs the program you specified when
CREDIR has finished running.
/RUNCOR:n Runs the program you specified with /RUN
in nK of memory when CREDIR has finished
running.
/RUNOFFSET:n Runs the program you specified with /RUN
with an offset of n. If you omit the
switch, the default is 0. If you
specify the switch, but omit a value for
n, the default is 1. If the offset is
1, the file uses an indirect command
file.
/STRS Searches for the SFD in all structures
in your job's search list, and uses
every occurrence.
Characteristics
The CREDIR program:
Destroys your core image.
Requires LOGIN.
Places your terminal at user level.
Examples
1. The following example shows the creation and use of an SFD
and directory paths.
Show a list of all the files in your UFD with a file
extension .TST.
.DIRECT *.TST<RET>
NUMB TST 0 <055> dd-mmm-yy DSKC: [27,5434]
109 TST 5 <055> dd-mmm-yy
FILL TST 1 <055> dd-mmm-yy
PAY3 TST 1 <055> dd-mmm-yy
TOTAL OF 7 BLOCKS IN 4 FILES ON DSKC: [27,5434]
Run the CREDIR program. Create a sub-file directory called
TEST. Use the /EXIT switch to exit from CREDIR.
.R CREDIR<RET>
Create directory: [27,5434,TEST]<RET>
CREATED DSKC:[27,5434,TEST].SFD/PROTECTION:775
Create directory: /EXIT
Request a list of all your files named TEST.
.DIR TEST.*<RET>
TEST FOR 1 <055> dd-mmm-yy DSKC: [27,5434]
TEST SFD 1 <775> dd-mmm-yy
TOTAL OF 2 BLOCKS IN 2 FILES ON DSKC: [27,5434]
The directory shows an SFD named TEST.
Use RENAME to transfer all files with the extension .TST from
your UFD to your SFD.
.RENAME [27,5434,TEST]=*.TST<RET>
FILES RENAMED:
DSKC:NUMB.TST
DSKC:109.TST
DSKC:FILL.TST
DSKC:PAY3.TST
Show that your UFD no longer contains the files with the
extension .TST.
.DIR *.TST<RET>
%WLDNSF No such files as DSKC:*.TST[27,5434]
Show that the files have been transferred to the SFD
[27,5434,TEST].
.DIR [27,5434,TEST]<RET>
NUMB TST 0 <055> dd-mmm-yy DSKC:[27,5434,TEST]
109 TST 5 <055> dd-mmm-yy
FILL TST 1 <055> dd-mmm-yy
PAY3 TST 1 <055> dd-mmm-yy
TOTAL OF 7 BLOCKS IN 4 FILES ON DSKC: [27,5434,TEST]
2. The following example shows the use of CREDIR with the SCAN
switch /PROTECTION.
.R CREDIR<RET>
Create directory: DSKB:[,,A,B,C]/PROTECTION:755<RET>
CREATED DSKB:[27,4072,A].SFD/PROTECTION:755
CREATED DSKB:[27,4072,A,B].SFD/PROTECTION:755
CREATED DSKB:[27,4072,A,B,C].SFD/PROTECTION:755
Create directory: /EXIT
