Making implicit and explicit selections
File-AID for Db2 Object Administration’s CUA-like interface offers two selection methods: explicit and implicit. Explicit selection is made one of two ways:
- Type an S next to the item you want to select. The S is typed over the numbers in the sequence area. This method is valid in windows that list items for selection, such as a menu.
- If the window has a column with the heading Command, you can enter the selection command in the COMMAND field. For example, in the Object Main Menu, the DATABASE selection has a command of DB. Enter DB in the COMMAND field.
Implicit selection uses cursor positioning to point to the command or function to execute. Move the cursor into position, then press Enter. The following describes some of the functions you can perform using the cursor and the Enter key:
- Selecting an item from a menu. Any item under the column heading Selection can be selected by placing the cursor on it and pressing Enter.
- Selecting a command for execution. In the Help windows that list valid commands, you can place the cursor on the command you want and press Enter.
- Resizing a window. The COMMAND prompt in every window is a toggle for window sizing.
- Removing a window by placing the cursor on the bottom border and pressing Enter.
- Executing a window’s contents (such as SQL) by placing the cursor on the top border and pressing Enter.
- Scrolling data displayed in a window by placing the cursor on a scrolling character and pressing Enter. See Scrolling Characters.
- Specifying a column for commands that control columns. See Controlling Window Columns.
- More information about window elements that provide implicit selection is in Common Window Elements.
Using a mouse
On certain terminals, using a mouse simplifies implicit selection. If you have a mouse, place the cursor on the window element or field and click the appropriate mouse button for Enter. You can also use the mouse to move the cursor to another window or field prior to pressing a PF key that uses implicit selection, such as <Help>.
For those commands and functions that open a new window, you can use the mouse to place the upper-left corner of the new window. The mouse button for Enter may also be used after entry of a command or input value to signal transmission of data to the computer.
