Re: Problem with non QUALIFIED DS

There are three problems with the pointer-based-template approach -
both solved by the "real" template support in 6.1

1) A based DS cannot specify INZ values.

2) The compiler cannot detect that you didn't really mean to reference
a field in the template. You won't find this out until run time when
it goes book with a pointer exception. Which of course is only a
problem for people who don't test fully <grin>

3) The cast majority of RPGers on seeing the BASED keyword will go
"What the ... " - I used to teach this technique in my sessions on the
D-spec but have all but dropped it (and relegated it to notes pages)
because such a large percentage of the audience just glazed-over when
they saw it.

Thank goodness Barbara added the real template support!

Ah - understood - I just put some dummy pointer name in the data
definition when making a template, in effect - just as you say, no
need
for explicit declaration of the pointer.
