o  You can only use this directive within data or mixed psects
       (psects that have either the NOEXE or MIX attributes).

    o  If automatic data alignment is enabled, this directive aligns
       the current location counter to a longword (32-bit) boundary
       before allocating storage.

    o  You can define a 32-bit address item using macros and the
       .LONG directive. For example:

       .macro address_32 item
       .long item
       .endm address_32
