Editing Basic Assembly Programming (section)

===== Moving Data Around =====

We said we want to complement the value in register 0. <code>loadi</code> would overwrite that value, so we need to save it in a different register first. Registers 1, 2, and 3 will be used for logical operations, so we’ll save it in register 4. Turing Complete should have automatically given you the mnemonic <code>0to4</code> for “moving” the value in register 0 to register 4. Note that this overwrites register 4, but ''does not'' change register 0. The operation is a copy-and-paste, not a cut-and-paste. Despite this, the typical assembly term for this operation is a '''data move''', '''register move''', or simply '''move'''. I recommend using the bitwise-or trick discussed above to make mnemonics for each source register and each destination register and then write <code>move|s0|d4</code>.

Some architectures use the mnemonic <code>mov</code> instead of <code>move</code>, and others use <code>load</code>.
