assembly - Does referencing constants without a dollar sign have a distinct meaning?

Question

I wrote:

mov 60, %rax

GNU as accepted it, although I should have written

mov $60, %rax

Is there any difference between two such calls?

Answer 1

Yes; the first loads the value stored in memory at address 60 and stores the result in rax, the second stores the immediate value 60 into rax.
