'
     I''ve been told that my'
	(MOVD ''TRUE ''BREAKCHECK)'
is undesirable because of NLSETQ forms in the system code.  Jon L White'
suggests I set system global HELPFLAG to BREAK!--a strategy I''ve tried before.'
According to the IRM (p 9.11) "If HELPFLAG=BREAK!, a break will always occur'
following an error."  If only it were true.  Doing'
	(RPAQQ HELPFLAG BREAK%!)'
doesn''t work as advertised.  I can get interaction like'
'
	52_(FOOBAR X)'
'
	UNDEFINED CAR OF FORM'
	FOOBAR'
'
	53_HELPFLAG'
	BREAK!'
'
without breaking.  I am therefore still stuck with the'
(MOVD ''TRUE ''BREAKCHECK), must redefine SMARTARGLIST, and count on'
the SINGLEFILEINDEX package to work properly.'
