Managing Files With TACL
Changing Your Default Values
Each user has a set of current and previous default values. Each set of defaults includes a
value for:
System (initially, the system where you log on)
Disk volume
Subvolume
File security (see
Your saved defaults are in effect when you log on and are your starting point in the
system. You can change your saved default system, volume, subvolume, and file
security with the DEFAULT program.
Your current defaults define your present location or frame of reference in the system, as
you have changed them from your saved defaults since you logged on. During a TACL
session, you can:
Move around on the system or network by changing your current system, volume,
and subvolume defaults, using the VOLUME and SYSTEM commands
Check your current location, using the WHO command
Display your current defaults in your command prompt, using the SETPROMPT
command
File-Name Expansion
When you specify a partial file name in a command, the operating system uses your
current default values to supply missing parts of the file name. This adding of parts to
file names is known as file-name expansion.
For example, if your current default node is \WEST, default volume is $WRLD, and
default subvolume is GLOBE, to purge the file \WEST.$WRLD.GLOBE.SOURCE:
20> PURGE SOURCE
Using file-name expansion, the operating system assumes that the complete file name is
\WEST.$WRLD.GLOBE.SOURCE.
However, the TACL program will not supply a default subvolume name when you
supply only a volume name and file identifier, as in $VOL1.MYFILE.
Changing Your Current Default System, Volume, or Subvolume
(VOLUME Command)
To change the current default subvolume from $GERT.STEIN (on your home system) to
the subvolume RHALL on \LONE.$WELL:
1> VOLUME \LONE.$WELL.RHALL
