#### 2.2.6 Literal constants ¶

MIXAL allows the introduction of literal constants, which are automatically stored in memory addresses after the end of the program by the assembler. Literal constants are denoted as `=wexp=`, where `wexp` is a w-expression (see W-expressions). For instance, the code

    L         EQU   5
              LDA   =20-L=

causes the assembler to add after the program’s end an instruction with contents 15 (‘`20-L`’), and to assemble the above code as the instruction `LDA a`, where `a` stands for the address in which the value 15 is stored. In other words, the compiled code is equivalent to the following:

    L         EQU  5
              LDA  a
    ...
    a         CON  20-L
              END  start
