All banks in the YBOS format are identified by a pair (TRY_Bank_Name, TRY_Bank_Number), which is encapsulated as TRY_Bank_Key in Trybos. Bank searches use the method TRY_Bank_Key::operator ==() to determine if two keys are considered a match.
Banks with `D' as the last character in their name and with bank number of 100 are assumed to have their data in a ``squeezed'' state. This does not affect Trybos behavior at present, but it is an issue for backward compatibility with YBOS software and software associated with squeezed data formats.
