1 Line_editingYour terminal has special keys that allow you to recall and edit previous commands. These keys are described below. Note that some of these keys may not be available on your keyboard. Recalling Commands ------------------ The system saves and allows you to access up to 254 of your most recently entered commands. The size of the recall buffer is 4Kb, which will store approximately 80 commands at 48 characters each. If the length of stored commands makes it necessary, one or more of the oldest commands will be removed from the recall buffer to make room for the most recent command. Use the up arrow or Ctrl/B keys to recall previously entered commands. Use the down arrow key to reexamine a command that you had retrieved using up arrow. If you are supplying commands or data to a program or utility, the system saves and allows you to access only your single most recently entered command. Editing Commands ---------------- To enable the editing keys, enter the following command: SET TERMINAL/LINE_EDITING You can add the /OVERSTRIKE or /INSERT qualifiers to the command to specify the default editing mode that you prefer. The /OVERSTRIKE qualifier causes a character that you type to be written over the character that the cursor is currently pointing at.
