Improvement to Test Series and Boot Sequence
Start using the LinkReg in Link, LinkE
[See PT20:dec20-patches.sl]
Improve portability of FUNCTION-PRIMITIVES.RED
[See TEST-FUNCTION-PRIMITIVES, using *JCALL for all.
Maybe go to SYMFNC=ADDRESS table ?]
May need to add a new CMACRO or two, or expand CMACRO's, to permit
indirect JUMP via a register/location, to define CodePrimitive().
Modify TEST5 and TEST6 to use the various portable APPLY etc.
Add BINARY IO tests to I/O. Perhaps as a file of LAP to read in?
Define a FASLIN/FASLOUT tester.
