Creating and Using DEFINEs
A DEFINE is a named set of attributes and values that let you specify information for a
process before you start the process.
The DEFAULTS DEFINE is a simple example; this DEFINE contains your default
node, volume, and subvolume names, which the system uses to expand your partially
qualified file names.
There are several advantages to using a DEFINE:
•
Convenience. For example, a MAP DEFINE lets you substitute a logical name for
an actual file name. It’s easier to use a DEFINE name such as =CUSTOMERS than
an actual file name such as \NY.$ACCNTS.CURRNT.CUSTNMES.
•
Saving time. Setting attributes for a spooler job with a SPOOL DEFINE is faster
than setting the attributes with Peruse after the job is on the print queue.
•
Using a TAPE DEFINE lets you access labeled tapes (if labeled-tape processing is
enabled for your system).
To use a DEFINE, you should be familiar with the TACL program, including its
relationship to other processes running on your system. See
Section 4, Starting and
Controlling Processes With TACL .
Using DEFINEs with FUP, labeled tapes, and Backup and Restore is described in
Section 7, Using FUP for Basic File Management , Section 10, Using Labeled Tapes ,
and Section 11, Backing Up and Restoring Disk Information , respectively.
