Line command fields can take many forms. Some have headings, some do not. Most are blank, but some contain single quotation marks or sequence numbers. For some, you type one character; for others, you type up to nine characters (even typing over data set names). Table 1 shows the functions that provide the line command fields.

The line command field for member selection lists is blank and has no heading. This includes typical member lists, which have a 1-character line command field, and the member list displayed when you use option M of the Data Set List utility, which has a 9-character line command field.
Quotes appear when you create a new data set or member, or when you insert one or more lines. Sequence numbers appear if you have NUMBER ON in your Edit profile.
Data set lists with 9-character line command fields allow you to type over data set names, thus extending the length of the fields to allow you to type long TSO commands, CLIST names, and REXX exec names. For information about entering TSO commands, CLISTs, and REXX EXECs in a line command field, see the Data Set List Utility (Option 3.4) topic in the z/OS V2R2 ISPF User's Guide Vol II. Also, the rules for entering TSO Commands, CLISTs and REXX EXECS from within ISPF are described in the Command (Option 6) topic in the z/OS V2R2 ISPF User's Guide Vol II.
