Line 1,288: =={{header\|MIPS Assembly}}== The register <code>$0</code> or <code>$zero</code> always has a value of zero and cannot be changed. Any attempts to load a nonzero value into this register will have no effect. This makes it useful as a "garbage bin" of sorts. When multiplying two registers, the product is always stored in the <code>$HI</code> and <code>$LO</code> registers. Their contents can be read into your standard registers with the commands <code>mfhi $reg</code> and <code>mflo $reg</code>.
