Active help is given if parameter values needed to execute a function are missing. A selection window containing all possible parameter values is displayed.
Active Help is available for all input fields marked with an asterisk. If an asterisk is entered in such a field a selection window is displayed. A selection window will also be displayed if a parameter is mandatory and the field is left blank or an invalid value is entered.
A sample active help window is shown below. An asterisk has been entered in the field File type of the File Maintenance screen. The valid file types are displayed in a selection window.

The following rules apply when using selection windows.
A list of valid values may exceed the size of the window. All, Top, More or Bottom in the top or bottom line indicate if and how a list of values exceeds a window. The following commands can be entered in the command field of a selection window:
| + | scroll down one window |
| ++ | scroll to bottom of list |
| - | scroll up one window |
| - - , top | scroll to top of list |
| PF3 or . | quit window |
Note:
The commands ++ and -- are not available if the data
displayed in a selection window is read from the dictionary.
Values can be chosen from selection windows in different ways:
by placing the cursor on the desired value and pressing ENTER
by marking them in the first column and pressing ENTER.
Selection windows are especially useful when selecting objects from the dictionary. Asterisk notation can then be used. All objects that can be specified in the specific context are displayed. See also the section Using Selection Windows for an overview of when selection windows can be used.
Selection windows in which more than one code, value or option can be chosen are closed with PF3 or '.'. For example: the Output options window. Selection windows in which one code or value is chosen are closed by confirming the selection with ENTER. For example: the File types selection window shown in the screen above.
Note:
It is not possible to select a value by entering the
respective code in the command field (==>) in the bottom line of selection
windows.
Context-sensitive online help information can be displayed by entering a question mark in the first field of a menu or from the Help Main Menu. Both forms are described in the sections below. See the following list for an overview of topics:
A topic list is displayed at the beginning of most help texts. To get more information on the topic you are interested in, position the cursor on that topic and press ENTER.

The Predict online help system uses the enhanced scrolling and scan functionality of the Software AG Editor. For more information see Software AG Editor in the section Editors in Predict in the Predict Reference documentation.
Online help texts can be changed by users. A special editor is provided for this purpose (see Maintain Predict Help Texts in the section Special Functions in the Predict Administration documentation).
Each menu has an associated help text that describes the function or functions invoked from that screen. The help text can be displayed by entering a question mark in the first field of the menu.
A question mark entered in the command line displays a series of help screens which explain the syntax and functions of the commands.
A more general access to the Predict help system is provided via the Help Main Menu which is displayed by entering a question mark in the Function field of the Predict main menu.
