awk: field $() is not correct


        I am writing an awk script and for several lines of the script
I receive the error:

awk: field $() is not correct

In some cases, by rearranging the lines (ie removing tabs, etc...) 
these errors go away.  What is causing the error and what can
I do to correct it?


 The error can be recreated as simply as this:
        print scanning file...
{print $0}
END   {
                print all lines processed

If this is in a file called awktest, the command
awk -f awktest  filetocat
will exit normally if the last line of filetocat is a carriage return.
In other words, if EOF is reached before a carriage return, the error
         The problem apparently does not occur if you have FS = " " 
(default) instead of setting FS = "".  When awk runs, it parses each 
line for arguments.   By setting FS = ""  the customer was hoping to 
increase efficiency by not having to parse the list of arguments 
into fields.
        Adding the return at the end of the last line
clears up all occurrences of the error.
