Process Definition Commands
Introduction
This section describes the syntax and semantics of the Define Process commands. The
Define Process command library provides a set of commands to the TACL command
interpreter. The library is available to you when you log on to your system in the same
way as your other TACL library files.
Command Introduction
The commands in the Define Process library allow you to define, start, stop, and delete
a process in any network node to which you have access. This means that you must
have remote passwords established between your system and all other systems that you
wish to access. Refer to the Guardian User’s Guide for information on remote
passwords.
You can supply input commands interactively, one line at a time, or from a file or
variable. You can view or delete input and output, or save it in a file or in a variable.
Table 2-1 lists all the Define Process commands and gives a brief description of the
function of each command. The remainder of the section provides complete
descriptions and syntax for each command, and the syntax for invocation of a defined
process. The following table and the complete command descriptions are listed
alphabetically.
