Specifying Symbolic Names
HP SRC has a new keyword that you can use when you wish to have access to
the head revision of a file. This keyword, $HEAD, can be specified in
the REV parameter whenever you wish to retrieve the head revision but
don't know the exact revision number.
In previous versions of HP SRC, symbolic names had to begin with a letter
followed by any printable ASCII character except a comma, semicolon,
colon, hyphen, and a single or double quotation mark. Now left and right
brackets ("[" and "]") are also invalid in symbolic names.
In addition, symbolic names are no longer case sensitive. All symbols
that are lowercase, whether they are new or existing, will be shifted to
uppercase.
