Each user has a queue of saved text that CANDE maintains for reference. The most recent saved text can be edited and processed as the next line of input. The commands provided for listing and editing saved text are ?SHOW, ?EDIT, ?REPEAT, and ?RETRIEVE.
Each normal line of input becomes the current saved text. A normal line of input begins with either
-
A character other than the control character defined for the user's station
-
A command other than a help-mode command.
Each entry in the queue is then moved up one level. If the saved text queue contains the maximum number of entries, the oldest entry is discarded. The maximum number of entries that can be saved in the saved text queue can be altered by the CANDE control command ?DEPTH. You must be a CANDE control station to use the ?DEPTH command to change the saved text queue entry limit. The maximum number range from 0 to 20, inclusive. Refer to the CANDE Configuration Reference Manual for more information about the ?DEPTH command.
If a line of input contains more than one CANDE command, each command is entered separately in the saved text queue. If a command does not complete successfully, the most recent saved text entry contains the failed command. Commands that follow the failed command are either part of this entry or are the first entry in the input queue (depending on the nature of the failure).
Throughout this manual, the use of saved text without a queue entry number refers to the most recent entry.
