Referring to a File in a Different Group

To refer to a ￿le in a di￿eren t group in the accoun t you are logged onto, use the follo wing standard ￿le reference format:

￿lename/lockword.groupname

where groupname is the name of the group where the ￿le resides. F or example, y ou can refer to the ￿le described in the example abo ve, residing in a group named SEPT, by specifying:

STATUS/MY.SEPT

Referring to a File in a Different Account

To refer to a ￿le in a di￿eren t account than the one you are logged onto, use the following standard ￿le reference format:

￿lename/lockword.groupname.accountname

where accountname is the name of the accoun t where the ￿le resides. F or example, y ou can refer to the ￿le described in the example abo ve, residing in an accoun t named MANU, by specifying:

STATUS/MY.SEPT.MANU

Session and Batch Modes

This section describes ho w to use sessions and jobs on a 900 Series HP 3000. A detailed description of the steps in volved in program development are given in Chapter 3 "Program Development."

The two ways to perform tasks on a Series 900 HP 3000 system are session mode and batc h mode. Session mode is in teractive. In other words, you log on to the system, it prompts y ou with information displa yed on the screen to determine what y ou want to do (or tell y ou what it has done), you enter information telling it what y ou want to do, and the system executes your commands. Session mode is dynamic; y ou can submit commands that can alter the outcome of your task, as y ou go.

Batch mode requires that y ou set up a job that y ou can submit all at once to the system for processing. The job con tains all the information necessary for the system to perform y our task: a log on, a list of commands to execute, and an end-of-job signal. When y ou submit a job in batch mode, you cannot alter the outcome of the task. The job will run to completion (assuming it does not end abnormally) without an y opportunity for y ou to change the commands in the job.

You can use the MPE/iX command :STREAM to initiate a job, once y ou have placed all the instructions for the job in a ￿le. This job stream is independen t of the session or job that originated the ￿le. You can use it to initiate a job directly from a curren t session or from a disc ￿le.

Almost all MPE/iX commands execute in either mode. Some giv e slightly di￿eren t information depending on the mode in whic h they are executed, and some are totally interactive and are ignored in batc h mode.

Figure 1-9 shows a comparison of the commands that begin and end a session and job.
