Slava, Doug,
Thanks for the tips.
I've now ensured that the arguments are consumed.
Using print flush instead of . flush makes no difference
in this case, unfortunately. I get the same result; "callbacked"
is printed only once.
I'll keep working on it.
I have a little test DLL to test callbacks, so I'll refine my
Factor callback skills on that.
I take it that there is no problem returning the integer 1
and that it will be converted to a char for me by the
definition below.
Thanks again,
Anton.
