Function Keys
HP ALLBASE/4GL displays application and system selections on eight
function key labels located along the bottom of the screen. Each
function key label indicates the function available if you press the
function key. With HP touchscreen terminals you can select the function
key facility by touching the function key label.
Standard Function Keys
The HP ALLBASE/4GL administrator application has four standard function
keys associated with every screen except the sign-on screen. They are f5
to 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.
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 for more details.
f6 Activate Item (menus) Confirms your menu selection and runs the
selected item.
f6 Commit Data (data screens) Confirms your data entry and
terminates 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 be the previous menu in terms of the
HP ALLBASE/4GL menu hierarchy. This function key returns you to
the menu from which you accessed the current screen.
System Keys Function Key Set
By pressing the System Keys function key on any HP ALLBASE/4GL screen,
you can display four sets of system function keys. These are the system
keys function key set, the name recall function key set, the more keys
function key set, and a second more keys function key set. Pressing the
System Keys function key on an administrator screen loads the following
set of function keys.
f1 Main Menu Returns you to the administrator main menu.
f2 Name Recall loads a set of function keys that let you scroll
through the names of items that are defined for a field type (the
item type expected in the 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 for more details.
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.
More Keys Function Key Set
If you have loaded the system keys function key set by pressing the
System Keys function key on an administrator screen, pressing the More

f1 Screen Printing Displays the screen printing keys, allowing you
to print an image of the current screen on the system printer or
a slave printer attached to your HP terminal.
f2 Op. System Suspends execution of HP ALLBASE/4GL and
temporarily runs the MPE/iX command interpreter program. When

f3 ISQL If HP ISQL is installed on your system, pressing this key
suspends execution of HP ALLBASE/4GL and executes ISQL. When you
exit from ISQL, you are returned to HP ALLBASE/4GL.
f4 ALLBASE QUERY If HP ALLBASE/QUERY is installed on the system,
pressing this key temporarily suspends execution of HP

When you exit from HP ALLBASE/QUERY, you are returned to HP
ALLBASE/4GL.

press this function key, HP ALLBASE/4GL displays a warning
message, allowing you to complete or reverse the transaction
before starting HP ALLBASE/QUERY.

screen or field.
