There are four different levels of help.
The first level of help displays any multi-line error messages. A single message is shown on the main screen but if there is more than one line of messages they are saved and the main screen displays:
“TB-5003W Enter Help command for a display of 2 lines of messages.”
When this message appears, press <PF1> to read the messages.
If there are no multi-line error messages, this help level is skipped and the second level is entered directly.
The second level of help is optional and is dependent on the attributes of the field for which help is being requested.
If the field has a list of all possible values associated with it, this level of help will display that list and a value may be selected.
If the field contains a library name, this level of help will display a list of the available library names that may be selected.
If the field contains a table name, this level of help will display a list of the available table names that may be selected. To move one of these values or library or table names into the field, use the <Tab> or <Newline> key to move to the desired entry, then insert the S (SELECT) line command to the left of the entry and press <Enter>, or, simply press <Enter> without the S.
The third level of help contains short explanations intended to assist a user when entering data on the screen or using a particular menu item.
The fourth level of help contains tutorial material intended for new or occasional users.
Typing HELP, or pressing <PF1> repeatedly, moves you through these levels in the appropriate order: level 1, level 2, level 3, and then level 4.
