2.4 Keywords

Keywords are reserved words that are used to denote special operations or are part of statements. They must not be used as identifiers. The keywords are

    and       do        elif      else      end       fi
    for       function  if        in        local     mod
    not       od        or        repeat    return    then
    until     while     quit 

Note that all keywords are written in lowercase. For example only else is a keyword; Else, eLsE, ELSE and so forth are ordinary identifiers. Keywords must not contain whitespace, for example el if is not the same as elif.
