/kh       Maximum number of symbols allowed

          /khnsymbols

          The /kh option sets the maximum number of symbols that your
          program can contain. If you don't use this option, your program
          can only have a maximum of 8,192 symbols; using this option
          increases the number of symbols to nsymbols, up to a maximum of
          32,768.

          Use this option if you get the 'Out of hash space' message when
          assembling your program.

          You can also use this option to reduce the total number of
          symbols below the default 8,192. This releases some memory that
          can be used when you are trying to assemble a program but don't
          have enough available memory
