Customized Sign On You can display a customized logo window when an HP ALLBASE/4GL application is run with the -l command line option. The -l option takes two arguments: logo_screen and logo_application. The argument logo_screen is the name of the window that you want to display on the sign on screen. The argument logo_application is the name of the HP ALLBASE/4GL application in which logo_screen is defined. If logo_application is specified you must precede it with a colon (:). If the -a and -u options are used on the same command line, the -l option and its arguments are ignored when HP ALLBASE/4GL starts up. However, the -l option is processed when you return to the sign on screen from within the developer application or the end user application. The screen logo_screen must be a window. If it is a menu or a data screen, HP ALLBASE/4GL ignores it and displays the standard HP ALLBASE/4GL logo screen. Use the HP ALLBASE/4GL screen painter to create the window. The screen cannot contain any data input or display fields, and the only valid system items for this window are the *DATE and *TIME communication area fields. Only lines 1 through 21 are displayed on the screen. The top line of the window is displayed as the second line of the sign on screen (the Hewlett-Packard copyright notice and product part number occupy the top line). If the custom window extends beyond line 14, HP ALLBASE/4GL may overwrite parts of the window when it displays the user name/password and application name/password fields. HP ALLBASE/4GL searches for logo_screen in the application logo_application. If logo_screen does not exist in logo_application, HP ALLBASE/4GL searches in the application HPlogo for logo_screen. If logo_screen is not found in either of these applications, HP ALLBASE/4GL searches for a window named logo in logo_application, and then in the application HPlogo. If you omit logo_screen from the command line, HP ALLBASE/4GL searches for a window named logo. If you omit application_name from the command line, HP ALLBASE/4GL only searches in the HPlogo application. If you use the -l option with no arguments, HP ALLBASE/4GL searches for a window named logo in the HPlogo application. If you do not specify the -l option at all, HP ALLBASE/4GL uses the standard sign on window.
