1. Database key wildcard search
- Posted by void at xs4all.nl

Is it possible to search a record with a partial key (key with
wildcards).
now we have:
rec = db_find_key("find_this_key")
a function like this would be very useful:
rec = db_find_key_wildc("find_th?s_???")
It should be possible to build such a function, but key_pointer
structure is a bit too complicated for me, can someone offer some help?
(I think an integer 'starting_rec' is needed to do multiple searches:
rec = db_find_key_wildc("find_th?s_???", starting_rec)

Better add a how_many_to_return also, so it can stop searching, and not
return 1000's of matches! And a way to find "find*_th*".
