A TRY_Bank_Name is a sequence of four ASCII characters. Each character in the name must be printable. There are otherwise no restrictions on bank names. The string representation of bank names is the fundamental one. An integer representation is also supported, but is not generally portable between operating systems with different byte-ordering of integers.
There is no wildcard support in TRY_Bank_Name. Since there are two record iterator classes which distinguish any-name and same-name iteration, a wildcard for TRY_Bank_Name is unnecessary and leads to less efficient name comparisons. Something like the wildcarding of Bank Names will be supported by way of a class TRY_Bank_Name_Set (to be developed) which will act much like YBOS name sets and subsets.
