Answers Answer 1. A validation table can contain 51 values. If you require more than 51 values, you can use the CHECK logic command in an after function on the field to validate the entered data against a number of tables. Answer 2. The scroll area of a screen is defined on the screen header screen. You can specify the first and last line of the scroll area, whether scrolling moves up or down, and a list of data items to be scrolled. You can only use a scroll area on a data screen. They are not available to windows and menus. Answer 3. HP ALLBASE/4GL moves data from the default data movement field to the screen field on display if the screen field buffer is blank. In this particular situation, "000" is moved to the option screen field to allow the user to add option number 000 for a new product. Answer 4. The screen header screen contains a field called Window Starting Line Number. You specify the starting line of the window in this field. The window is displayed from this line to the bottom of the screen. Answer 5. Function keys can contain any of the following items as an action. Your answer should include three of the following: * A process. * A function. * A help screen. * An internal HP ALLBASE/4GL action. * Another function key set. * A report. * A screen. * An external program. * A background process. * Nothing. Answer 6. The SCROLL command displays data on the appropriate scroll line of the current screen. It displays data on the first line of the scroll area if the scroll direction is down, and on the last line of the scroll area if the scrolling direction is up. Answer 7. A select list is a "virtual" HP ALLBASE/SQL table. It contains columns from one or more base tables or view, and each column is defined by a dictionary field specification. Column values can be computed, a constant, or taken directly from a base table column. Select lists are dictionary items in HP ALLBASE/4GL. Answer 8. If a screen field is also a field specification, you can link the help screen to the field using the Help Name field on the field specifications screen. You will need to regenerate any screen currently referring to the field specification. You can also link a help screen to a screen field on the screen field details screen if the field is not a field specification, or if you don't wish the help screen to be tied to every occurrence of the field specification on a screen. To link a help screen to a screen, enter the name of the help screen in the Screen Help Name field on the screen header screen. Answer 9. To initiate line drawing mode from the screen painter, display the Main Keys function key set, and press the Special Text function key. Then press the Line Drawing function key.
