how to write octal constants in MIPS (MARS assembler)

Question

I would like to specify to MARS that I'm entering an octal number as an immediate operand.

I know that it is possible with Hex- Something like:

li  $t0, 0x24    #this is ASCII '$'

Is it possible to do the same with Octal?

Answer 1

Just prefix the immediate with 0, like in C:

li $t0, 024
