Using data sets in line mode TSO/E

In line mode TSO/E, you can do the same data set management tasks you did using ISPF/PDF. The tasks we discuss in this section are creating data sets, listing information about data sets, and deleting data sets.

REMEMBER

When using TSO/E commands:

You can stop a process by pressing the attention interrupt key (PA1). For example, if you see a message you don't understand and want to stop doing what you started, press PA1.
In examples of commands, the words you must type such as commands and keywords are in capital letters. The variable words such as data set names and user IDs are in lower case letters.
```
COMMAND KEYWORD(data set name)
```
When specifying a data set name in a command, you do not need to include the first qualifier if it is your prefix. Thus to specify data set PREFIX.TEST.DATA, you can type: TEST.DATA. When you include the first qualifier, you must enclose the data set name in single quotation marks: ‘PREFIX.TEST.DATA’.
When a command processes successfully, you typically see another READY message. When a command does not process successfully, you see an error message.
