 . Notes

 .  Reserved words cannot be used for variable, procedure, or
    user-defined function names.

 .  Reserved functions are built into the compiler and therefore cannot
    be redefined by an application.

 .  Abbreviations of reserved words and functions of four or more
    characters are also reserved.

 .  All identifiers that begin with one or more underscore characters
    (_) are designated as system identifiers and are therefore reserved.
