Dear Stan,
I'd be delighted to have the following filter :
Let's define the pick4 signature of a 6/49 lotto ticket as the middle four last digits(could be any 4-subset of the 6 positions). The filter will accept a ticket if its signature comes from a pick4 ticket file (for eg. saved from a pick4 lotto in EL).
Example : ticket 23 27 28 34 38 43 has signature : 7 8 4 8
match file has to contain one line with 7848 (strictly in that order) for the ticket to be accepted.
Thanks.
