[L]ist
     Lists the message as it exists, can be called anytime during 
     the editing session.

[E]dit
     The message line editor is probably one of the most    
     misunderstood functions in message entry. Because of the
     line by line nature of serial communications a full screen
     editor cannot be implemented. Instead, a search for text to
     be changed is followed by insertion of the corrected text.
     The terminology used is OLDSTRING for the text to be
     replaced and NEWSTRING for the new text. After asking for 
     the line number to be edited, WILDCAT! needs to know what
     needs to be changed. The syntax for this procedure is 

     OLDSTRING;NEWTSTRING  (note the semicolon between the two words).

     This command is translated as "Take the first occurrence of
     the characters OLDSTRING and delete them, then insert the
     characters NEWSTRING in the same location. For example, if
     the message line reads:

	"this is a message to shw how to use th Edit command."

     Obviously we need to change two errors, the word "th" for
     "the" and "shw" for "show". First lets fix "shw" by using
     the command "shw;show" which scans for the word "shw" and
     replaces it with "show". Now the harder correction. Notice
     that the first occurrence of the incorrect text "th" is
     actually a part of correct text "this" in the 1st word.
     Therefore we can't simply use the command "th;the" or the
     new message will read 

	"theis is a message...". 

     The proper method is to broaden the OLDSTRING search to
     include additional unique text such as 

	"use th;use the"

     Notice that we can replace any number of letters even with a
     shorter or longer NEWSTRING. 

     After an edit the caller is presented with the corrected
     line and allowed to make more corrections, if needed. A
     blank [C/R] terminates the Edit mode.

[I]nsert
     Allows insertion of new lines in the text. The user is
     prompted for the line number where new lines should be
     inserted. The selected line number moves down, and a new
     line is added at the chosen number. Any number of new lines
     will be inserted as word-wrap creates more new lines as
     needed.

[+] Subj.
     Pressing the plus key (+) allows editing the Subject line of
     the message in the event that it is incorrect or misspelled.

[S]ave
     After the message has been proofread and edited, the save
     command will update the message base with the message and
     appropriate carbon copies, if requested.
