It's not necessary to have the hex number corresponding to the binary number. Just to be for the same file.

>>It is a number in string format. Given a record with optional fields, each bit in the binary string corresponds to a field in the record. For example, if the fifth field is included, the fifth bit in the binary number is set on. If the fifth field is not included, the fifth bit in the binary number is set off. This binary number is then converted to hex and sent at the beginning of the record. When I get a reply record back, I have to do the opposite...convert from hex to binary to determine which fields have been sent. I may not always have 16 bits...it depends on the record type that is sent. Different record types have a different number of fields.

Yes, your right. Here's an example: FEA0 = 1111111010100000......this is right out of the record layout documentation sent to me from the other company.
