Function Keys
In addition to the selections displayed on menus, HP ALLBASE/4GL displays
application and system facilities on eight function key labels located
along the bottom of the screen.
You can select the displayed facility by pressing the associated function
key. The function keys f1 through f8 are located along the top row of
the keyboard.
With HP touchscreen terminals you can select a function key facility
directly by touching the function key label on the screen.
The HP ALLBASE/4GL developer application has four standard function keys
associated with every screen-the keys f5 through f8. The actions of
these keys are standard throughout HP ALLBASE/4GL and are not described
elsewhere in this manual unless they are significantly different from
those described below.
Standard Function Keys
The standard function keys and their actions are:
f5 System Keys Loads the standard function key set that enables
you to access a number of system and terminal utilities. Refer
to System Keys Function Key Set below.
f6 Activate Item (menus) Confirms your menu selection and executes
the selected item.
f6 Commit Data (data screens) Confirms your data entry and
terminates processing of the current screen.
f7 Help Displays the help screen associated with the current
screen or field.
f8 Previous Menu Returns you to the last menu displayed by the
system. This menu may not necessarily be the previous menu in
terms of the HP ALLBASE/4GL menu hierarchy. The previous menu
function key returns you to the menu from which you accessed the
current screen. If you selected the current screen by using
function keys or the menu bypass, you may not be returned to the
next higher menu in the hierarchy.
System Keys Function Key Set
Pressing the System Keys function key on a developer screen loads the
following function key set.
f1 Main Menu Returns you to the developer main menu.
f2 Name Recall loads a set of function keys that let you scroll
through the item names that have been defined for an active
field.
f3 Clear Screen Clears all fields on the current screen.
f4 Refresh Screen Repaints the current screen image, including the
contents of all fields.
f5 Previous Keys Reloads the standard set of function keys for the
screen.
f6 More Keys Loads the second set of system keys. Refer to More
Keys Function Key Set below.
f7 Help Displays the help screen associated with the current
screen or field.
f8 Previous Menu Returns you to the last menu displayed by the
system.
Name Recall Function Key Set
These keys enable a context-sensitive name recall function. If the
active field on a screen has a defined field type and item names
associated with the field, the developer can use this set of function
keys to recall the item names one at a time in the active field, to
complete partially entered item names, or to access a catalog display
screen that lists all of the names for a type or all the available types.
f1 First Item lets you return to the first item in the group.
f2 Previous Item lets you return to the previous item in the group.
f3 Next Item lets you see the next item in the group.
f5 Previous Type changes the display to the previous item type.
f6 Next Type changes the display to the next item type.
f7 Help displays the help screen for this screen.
f8 Restore Field restores the original field display.
For more information about the name recall function, refer to the "Using
Name Recall" section later in this chapter.
More Keys Function Key Set
If you have loaded the system keys function key set by pressing the
System Keys function key on a developer screen, pressing the More Keys
function key loads the following function key set.
f1 Screen Printing Loads the screen printing function key set.
These keys allow you to print a screen image on the system
printer, or on a slave printer attached to the terminal.
f2 Op. System Temporarily suspends execution of HP ALLBASE/4GL
and runs the MPE/iX command interpreter. When you exit from the
temporary session (by typing EXIT), HP ALLBASE/4GL processing
resumes at the point where you suspended it.
f3 ISQL If HP ISQL is installed on the system, pressing this key
temporarily suspends execution of HP ALLBASE/4GL and invokes HP
ISQL. When you exit from HP ISQL, you are returned to HP
ALLBASE/4GL.
f4 ALLBASE QUERY If HP ALLBASE/QUERY is installed on the system,
pressing this key suspends execution of HP ALLBASE/4GL and starts
HP ALLBASE/QUERY. HP ALLBASE/QUERY automatically connects to the
current application's database. When you exit from HP
ALLBASE/QUERY, you are returned to HP ALLBASE/4GL.
If the current application has an open ALLBASE/SQL transaction
when you press this function key, HP ALLBASE/4GL displays a
warning message, allowing you to complete or reverse the
transaction before starting HP ALLBASE/QUERY.
f5 Previous Keys Reloads the previous function key set.
f6 Catalog Display Displays the catalog display screen for the
application you are running. A general catalog display screen
can be accessed through any of the menus.
f7 Help Displays the help screen associated with the current
screen or field.
f8 Exit Terminates the current HP ALLBASE/4GL session.
