Introduction to Define Process

Introduction

The Define Process is a process that permits you to start up to 100 background processes

such as PUP, FUP, SPOOLCOM without having to exit the process that you are

currently working on. You must have access to the TACL process for using the Define

Process utility. Operators at the TACL screen can communicate with command

interpreters or other utilities and can use the Define Process commands to run several

background processes simultaneously.

Figure 1-1 is a simplified overview of the Define Process application.

TACL Screen

If available, the TACL screen provides all the existing capabilities of TACL (see the

TACL Programmer’s Guide) plus access to the Define Process library of commands.

You can use function keys on this screen to switch readily to other parts of the

application. Conversely, you can easily switch back to the TACL function, such as

checking the availability of a file and running a program such as PERUSE to check on

the printer status.

Define Process Library

The Define Process library is a library of TACL commands that permit the creation of

multiple subsystem control processes throughout the network. Such control processes

keep running as background processes, available for access by the operator without the

normal delays associated with starting a remote process. This essentially provides easy

access to all available management utilities that exist in a system or network.

The Define Process capability also enables you to create composite commands that

direct commands to one or more subsystem control processes. This capability manages

the communication between operators and defined background processes through
