In Local Mode, the register-to-register and memory-reference instructions follow the scheme shown below:
This mode is equivalent to Compact Mode in terms of the accessibility of supplementary instructions to be dealt with in the following pages. Here, however, instead of allocating a large proportion of opcode space to short format memory-reference instructions, it is supplementary register to register instructions that are emphasized. Also, as with Simple Mode, the 32-bit group of operate instructions including subroutine jump and conditional jump instructions is completely present, but with modified opcodes.

Note also the use of the same compact memory-reference instructions as used in Scratchpad Mode, but with modified opcodes.
