The general assembler directives provide facilities for
    performing eleven types of functions. Some directives are only
    applicable within data psects (psects with the NOEXE and NOMIX
    attributes). Other directives are only applicable within code
    psects (psects with the EXE and NOMIX attributes). All directives
    are applicable within psects that contain either data and code,
    or both (psects with the MIX attribute). For information on the
    MIX assembly-time psect and any associated restrictions, see the
    description of the .PSECT directive in this chapter.

    The following table discusses these types of functions and their
    directives.
