Below is a brief discussion of the various error messages associated with the line Editor.
|col#?||Displays when a nonnumeric character is used in a syntax position that would ordinarily require a number.|
|Cmnd?||Indicates that an invalid Editor command was issued.|
|Eoi n||End of item occurs at line n.|
|L n||Indicates either the current line number (with the ? command), or the last line affected by an x command.|
|Not on file||Cannot find the requested item with the me command.|
|Seqn?|| Changes must be made from the top down. An f command clears this up.
Note: When this displays, the requested change does not take place.
|String?||Usually means that the second part of the replace string has been omitted or that the syntax for the me command is incomplete. Also displays when a nonnumeric character is used in a syntax position that would ordinarily require a number.|
|Top||Indicates that the line pointer is positioned at attribute 0, or the top of the item. (An i command issued here will insert before attribute one).|
|'ID' deleted.||(error message item-ID = 222)|
|'ID' exited.||(error message item-ID = 220)|
|'ID' filed.||(error message item-ID = 221)|
The most common error message is the seqn? message. It indicates that a change is being attempted to a line above a line that a change has been made. To correct this, use the f command, then try the same operation that previously failed.
