The alert character 3#3a, usually implemented as the ASCII BEL character, is not defined because is is used as an internal delimiter in the implementation. However, it is definable in terms of the DATR Chars library node in the unlikely event of being badly needed.

...defined:

This distinction does not need to concern the user, and is discussed for the sake of completeness. All builtin and external library functions are loaded by default and are accessed by means of the #uses directive. The default can be overridden by the command line switch -n if required. In the following description, no distinction will be made between builtin and external Zdatr 2.0 library functions, and both will be referred to as ``library functions''.
