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
