Decoding program

-----------------------------------

I've got the decoding part ok, but I need some help with the output

Here's what i have so far 

put "Enter a coded message with all letters offsetted by the number of" 
put "characters within the first word. " 
get code : * 

offsetkey := index (code, " ") - 1 
%decoding 
message := "" 
message2 := "" 
msglength := 40 
for aa : 1 .. length (code) 
    number := ord (code (aa)) 
    
    if not number = 63 and not number = 33 and not number = 44 and not number = 46 and not number = 58 and not number = 59 and not number = 45 and not number = 32 then 
        
        for xx : 1 .. offsetkey             
            number := ord (code (aa)) - 1  
            if number < 65 then             
                number := 90               
            elsif number < 97 and number > 90 then 
                number := 122               
            end if 
        end for 
    end if 
   
%OUTPUT 

 locate (14, 20) 
    if aa < msglength + 1 then 
        message := message + chr (number)   
    end if 
    if aa > msglength then 
        put message 
        message2 := message2 + chr (number) 
        locate (15, 20) 
        put message2 
    end if 
end for 



I need to make it so that when 40 characters are exceeded it goes onto the next line, no matter how many characters you have. 

The output cannot exceed 40 characters per line, if it does it goes to the next line.

No word can be broken (the word can't be started on a line and continued on the next)

First, you'll need to know how to search for a space.  Check out the String Manipulation tutorial.  You'll find a link to it in the Turing Walkthrough.
