10. Symbol Table

• For multiple data directives Assembler builds a symbol table

• Both offset (in bytes) and label refer to the allocated storage space in memory:

                                      ; label      memory
                                      ; name       offset
      .DATA                           ; --------   -------
      value    DW  0                  ; value         0
      sum      DD  0                  ; sum         2
      marks    DW  10 DUP (?)         ; marks         6
      message  DB  'The grade is:',0  ; message    26
      char1    DB  ?                  ; char1      40
