Fixed how index operands are assembled into PDP-10 instructions, which was an unexpectedly convoluted process (they are NOT masked to 4 bits, shifted left 18 bits, and OR'ed into the opcode; instead, they are computed as a 36-bit value whose left and right 18-bit halves are swapped and then ADDED to the opcode, which means that an instruction encoded with indexing may not end up using indexing at all, depending on where all those bits fall)

Changed the remainder operator from '%' to '^/', mainly because '%' must be allowed in MACRO-10 symbols instead, but also because '%' led one to believe it was a "mod" operator (it wasn't); added IFDEF support to the MACRO-10 Mini-Assembler; updated the Debugger's assemble command to recognize filenames with "KLM" extensions, too.
