Editor error messages.

Description

a brief discussion of the various error messages associated with the line editor.

col#? Appears when a non-numeric character appears in a syntax position that would ordinarily require a number.

Cmnd? Short for 'command?'. 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' (oops) command.

Not on file

Can't find the requested item with the 'me' (merge) command.

Seqn? Sequence? Changes must be made from the top down. An 'f' (flip) command clears this up. Note that when this appears, 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 merge command is incomplete. Also appears when a non-numeric character appears in a syntax position that would ordinarily require a number.

Top Indicates that line pointer is positioned at attribute 0, or the 'top' of the item. (An 'i' ('insert') command issued here will insert before attribute one).

Wrapup error messages:

'id' deleted. (error message item-id = 222)

'id' exited. (error message item-id = 220)

'id' filed. (error message item-id = 221)

Example

014 print customer.id
.i print
.12
012 print current.balance
.i
seqn?

The most common error message is the 'seqn?' message. It indicates
that a change is being attempted to a line 'above' a line in which a
change has been made. To correct this, use the 'f' ('flip')
command, then try the same operation that previously failed.
