<constant> and [<constant>] Are Semantically the Same

SUMMARY

While <constant> and [<constant>] are syntactically different (a constant and a constant within brackets), they are semantically the same. For example, the following statement:


   MOV ax, [100]

will move the value of 100 into ax, not the value that is at address 100.

Another example is using a constant offset in a segment override:


   MOV ax, ds:100     ; This will access the word at offset 100

   MOV ax, ds:[100]   ; This will do the same thing
