MessageName
 Usage
• symbol::tag is a name for a message.
Notes
• You can specify messages by defining values for symbol::tag. • symbol::tag is converted to MessageName[symbol, "tag"]. tag can contain any characters that can appear in symbol names. symbol::"tag" can also be used. • Assignments for s::tag are stored in the Messages value of the symbol s. • The following messages are typically defined for built-in functions:
| f::template | a template showing a typical case of the function | | f::usage | a description of how to use the function |
• ?f prints out the message f::usage. • When ?form finds more than one function, only the names of each function are printed. • You can switch on and off messages using On[s::tag] and Off[s::tag]. • MessageName[symbol, "tag", "lang"] or symbol::tag::lang represents a message in a particular language. • New in Version 1; modified in 4.
