no... I wasn't worried about changing anything with the POSITION.
My question was simply that I don't have to worry about garbage left in the buffer used for the key, or whatever the values are in the "right hand" part of the buffer used for the key.
so therefore, positioning at country "New York" (and nothing else) would give me the following key with the first Inquire:
"New York":"NY":"Bronx"
In some other systems, I've learned to explicitly fill the key such as:
KEY = Country$ + @0000@ + STRING("@00@",20)
so that the (assumedly LEN=2) StateProv string was "Null Filled", as was the (assumedly LEN=20) City name, to insure I got the right pointer.
like when doing ENCRYPT... if you don't pre-fill the string or the seed explicitly with spaces @20@, you might get junk which you wouldn't know until you did the DECRYPT
Thanx!
