Loop Counter Register
Microsoft DirectX 9.0 SDK Update (October 2004)

Loop Counter Register


The only register in this bank is the current loop counter (aL) register. It automatically gets incremented in each execution of the loop...endloop block. So it can be used in the block for relative addressing if needed and is invalid to use it outside the loop.
