     .space $PRIVATE$       ; this is how you specify spaces  
     .subspa $BSS$          ; this is how you specify subspaces
 _character_table
     .comm  1024
     
Better still, consider the following:

A source file called chartab.c, whose contents are the single line

   char _character_table[1024];

cc -c this file, and you get an object file that has a "common definition"
for your space. Portably.
