10.2. The Print Name

Every symbol has an associated string called the print name. This string is used as the external representation of the symbol: if the characters in the string are typed in to read (with suitable escape conventions for certain characters), it is interpreted as a reference to that symbol (if it is interned); and if the symbol is printed, print types out the print name. For more information, see the sections on the reader (section 22.1.1) and printer (section 22.1.6).

[Function]
symbol-namesym

This returns the print name of the symbol sym. For example:

(symbol-name 'xyz) => "XYZ"

It is an extremely bad idea to modify a string being used as the print name of a symbol. Such a modification may tremendously confuse the function read and the package system.
