SIZE             Return bytes used by variable                       Operator

  SIZE addr_name                        ; Ideal mode

    Returns the actual number of bytes allocated to the data variable (DUP
    byte count, if appropriate) if addr_name is defined in the current
    module (i.e. the number of bytes occupied by the first item after
    storage-allocation directives like DB or DW).

  SIZE addr_name                        ; MASM mode

    Returns the size of the subtype of addr_name
      (UNKNOWN (0), BYTE (1), WORD (2), DWORD (4), PWORD (6), QWORD (8),
      TBYTE (10d), SHORT = NEAR (0FFFFh), FAR (0FFFEh), structure_addr
      = size of structure)
    multiplied by the value of LENGTH addr_name.

    Examples:   theAuthor DB "Hemingway"
                twoLines  DB "Ln1",13,10,"Ln2"
                Echoes    DB 8 DUP ("Echo",13,10)
                aSize = SIZE theAuthor          ; Ideal 9, MASM 1
                lSize = SIZE twoLines           ; Ideal 3, MASM 1
                eSize = SIZE echoes             ; Ideal 6, MASM 8
                aLen  = LENGTH theAuthor        ; Ideal 1, MASM 1
                lLen  = LENGTH twoLines         ; Ideal 1, MASM 1
                eLen  = LENGTH echoes           ; Ideal 8, MASM 8


  SIZE struc_name/union_name/table_name ; Ideal or MASM mode

    Returns the number of bytes required to represent the structure /
    union / table.

  SIZE struc/table_member_name          ; MASM mode

    Returns the quantity TYPE struc / table_member_name multiplied by
    LENGTH struc / table_member_name.

  SIZE record_name                      ; Ideal or MASM mode

    Returns the number of bytes required to represent the total number of
    bits reserved in the record definition: either 1,2, or 4.

  SIZE enum_name                        ; Ideal or MASM mode

    Returns the number of bytes required to represent the maximum value
    present in the enum definition: either 1,2, or 4.

  SIZE segment_name                     ; Ideal or MASM mode

    Returns the size of the segment in bytes.

  SIZE type_name                        ; Ideal or MASM mode

    Returns the number of bytes required to represent the named type, with
    short and near labels returning 0ffffh, and far labels returning 0fffeh.
