MOVEA #OFF20 *IN,20 is clearly understandable when #OFF20 is defined by
standard as a named constant of 20 characters of character 0 and by standard
the first thing that is done after an EXFMT is to set off the eror
indicators on the screen.  We use this technique more because it is
absolutely clear what it does and it uses far fewer lines of code.  The fact
that the performance of MOVEA is better than SETOFF is irrelevant given the
nano-seconds of execution time difference.
