Batch File Line Continuation

CMD.EXE will combine multiple lines in the batch file into a single line 
for processing when you include the escape character as the very last 
character of each line to be combined (except the last). The default 
escape character is the caret [^].  For example: 

        echo The quick brown fox jumped over the lazy^
        sleeping^
        dog. > alphabet

You cannot use this technique to extend a batch file line beyond the 
normal line length limit of 1,023 characters.
