This command can be combined with the Compare GPRM operations for conditional branching. When combining, this command is executed only if the result of the comparison is true.

1) Compare to another GPRM register and SetGPRM
2) Compare to another SPRM register and SetGPRM
3) Compare to a constant value and SetGPRM
4) SetGPRM and Link
