am_cluster
         -  Memory cluster where all the clients live. Consider this memory
            pool where each allocation is of fixed size, requires no global
            arbitration and is incredibly fast upon chunk request.

am_fcluster
         -  Memory cluster that files  use. Can auto expand at any point as
            opposed to am_cluster.

am_links -  List of all links(wrapped files, dos_alp_file).

am_clilist
         -  A  list of all callers who  were granted  access to real files.

am_devname
         -  This  member points at the  device name. The name is colonless.

am_dol   -  This Doslist pointer is here just to make inter-function access
            quicker. It really points at the device node!

am_vol   -  Virtual device volume that is really a copy of am_dol, but acts
            as a fully qualified volume.

am_dp    -  Main DOS packet pointer, also here to make it all look simplier
            when dealing with nested calls.

am_last  -  As linkpoint really tries to maintain consistent file list that
            never  changes on addressation this member is serves  as a list
            terminator.

am_af    -  Root object(ST_ROOT). This  file although not  on the file list
            is a kickstart for other files.

am_isfs  -  Dynamic filesystem indicator. This toggles when linkpoint is to
            be stream device only.

am_wrprot
         -  Write protection indicator.

am_dfiles
         -  Discarded files count. This  is used to tell the used that some
            of the  files could not be mapped. The  info can be obtained by
            using  'Info'  command, where  Errors  field will reflect  this
            member.

am_filenull
         -  NULL in am_fileline position indicator.

am_fileline
         -  This  buffer is used to store real  file locations while making
            a list of wrapped files.

am_argline
         -  This buffer is used to store LPX  arguments who then get parsed
            by ReadArgs().
