Task-Related Commands
This chapter is an introduction to MPE/iX commands and their functions,
categorized by the task they perform.
The categories of tasks identified for MPE/iX commands are:
* Accessing Subsystems and Utilities.
* Command Interpreter Programming Tools.
* Communicating with Other Users.
* Executing User Programs.
* Managing Accounts, Groups, and Users.
* Managing Devices.
* Managing Files.
* Managing Jobs and Sessions.
* Managing Spooler Operations.
* Managing System Resources.
* Managing User/System Logging.
* Managing Variables and Job Control Words.
* Managing Volumes (Disk Drives).
* Using Command Files and User-Defined Commands.
* Using Computer Language Programs.
To use this chapter, first determine what task you want to perform, for
example, create a new account. Check the list above to find an
appropriate category, which in this case would be "Managing Accounts,
Groups, and Users". Turn to that category and you will find a list of
MPE/iX commands that perform tasks related to managing accounts and a
description of the particular function for each command.
Check that list to find an
appropriate functional description, which in this case is "Creates a new
account". Then check the lefthand column for the name of the command
that performs that function, which in this case is NEWACCT.
When you have located the command that most closely performs the task you
want to accomplish, turn to chapter 2 of this manual for complete
information about the syntax, parameters, operation, use, and examples
for that command. For your convenience, the commands in chapter 2 are
listed in alphabetical order.
