To avoid messing with the arrays I tried a dirty and quick hack based
in the suggested query (rewrite the define after printing what was
returned). Well, it says 256 so the define is unchanged. No idea why
it failed for some time, maybe then the ramp was other size in the
meanwhile (bigger to support all cards, then back to what each card
really does?). Anyway I will try to improve the code so the define can
go away.
Thanks for the tip and the reminder.
