Fixed (or rather, band-aided) a MACRO-10 regression assembling the nested macro test (/apps/pdp10/tests/macro10/TEST.MAC)

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)

Added a few PDP-10 byte pointer fixes, along with the ability to pass MACRO-10 text directly into the MACRO-10 assembler (use the Debugger's "as" command)

Lots of MACRO-10 improvements, DAKAM now assembles (but does not pass)

Well, that was brutal, but ALL the PDP-10 DAKAL multiplication and division tests FINALLY pass

I *think* all the PDP-10 DAKAL multiplication tests pass now. Division tests, alas, are a different story.

Fixed 36-bit multiplication in the expression parser so that, within the PDP-10 environment, it produces the same 36-bit results that a PDP-10 would produce (important for MACRO-10 compatibility)
|

Updated the PDP-10 DAKAK diagnostic page, and verified the ability to assemble (but not run) all the original DAKAK source files, after making further improvements to the built-in MACRO-10 Mini-Assembler

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.

PDP-10 multiply diagnostic testing finally underway; fixed one bug related to the KA10 (not that anyone really cares anymore)

Added another PDP-10 diagnostic (DAKAJ), which in turn required some more MACRO-10 support (eg, macro parameters with backslashes)

Fixed/simplified opASH() a bit; it wasn't preserving the sign bit in all cases, and converting the input from unsigned to signed and back again was more confusing than helpful
|

The shared expression parser now adapts to the (critically) different precedence of MACRO-10 operators

More robust handling of PDP-10 memory errors (so that when a file is assembled and loaded into non-existent memory, an error is generated); bumped the PDP-10 test machine to 32K words
|

Made the Debugger's assemble command more flexible (the target address is optional now; the Debugger will use whatever load and/or start addresses the file(s) specified instead)
|

Added support for MACRO-10 literal collapsing; it's not super-aggressive, but it's more than adequate for what DEC's diagnostics require
|

The expression parser now allows spaces inside expressions (a relaxation for certain MACRO-10 typos; eg, "- 1" where "-1" was expected)

Fixed MACRO-10 literal processing (literals need to be evaluated as early as possible, but not allocated until the end is reached)
