Appendix D. File Name Tokens
File name tokens are a feature of the platform server with which you can substitute generated values into file names when communicating between any combination of z/OS, Windows, and UNIX platform servers.
Given a file name that includes one or more tokens, the platform servers resolve the token or tokens (for example, date, time, and user) within the file name to the actual file name. This can be very useful when it is necessary for the file name to be unique or to follow naming conventions. Windows and UNIX resolve tokens on both the local and remote file names. While for requests initiated by z/OS, the tokens are resolved by z/OS for the local file name only. This means that if a token is specified in the remote file name, you must refer to the documentation for the remote system to get the list of supported tokens.
Instead of entering a standard file name, you enter a name that consists of tokens which are specified by a dollar sign ($) followed by the token name in parentheses. For example, $(LocalFileName).
