Hi,

I am needing some advice on how to calculate a reference key.  The function I have is
int getReferenceKey(int key)
the value of the key is calculated by the formula
key=(location index)*10+(type index.)

thanks.

The program I am constructing will have up to 100 entries, consisting of say 6 columns of information.  Each line of each entry needs to have a reference key assigned to it.

So just make some formula up and get a value from that.  You are already doing something like this according to your first post; simply chose another formula that generates a unique value.

If you have 100 entries, numbered 1-100 or 0 - 99, and six columns, numbered 1 - 6 or 0 -5, then a reference key could be entry * column with a little more 'spice' added to it.  Alternatively you could always use the address of each entry, that is guaranteed to be unique.
