MEMORY reports the size of your mud.
The 'Mobs' and 'Objs' lines REPORT the number of types of mobiles and objects,
not the number of instances currently in the game.
The 'Strings' line shows MEMORY used by area-file strings. These strings have
a maximum limit, which is also shown.
The 'Perms' line shows permanently allocated MEMORY blocks. There is no limit
on the number and size of these blocks.
