capsule/words.v4: the stack, comparison, shift, double, mixed and string words whose definitions DECOMPOSITION.md already gives and the mesh-node tests execute, now in the host node's vocabulary: 2SWAP 2OVER 2ROT 2>R 2R> 2R@ 2@ 2! -! 0<> 0> <> <= >= U< U> ABS MAX MIN WITHIN LSHIFT RSHIFT D- DABS D0= D0< D= D2* D2/ D< DMAX DMIN M+ M- CMOVE> MOVE FILL ERASE BLANK -TRAILING COMPARE SEARCH SCAN SKIP ?TERMINAL TRUE FALSE INVERT NOP - A shift count that is negative or as large as the cell is an error, as in v3 (code 9, "Shift count out of range"). - tests/test_host_quit.c: 36 sessions from the prompt that are transcripts of the v3 binary, and the cases where v4 keeps the standard (MOVE in cells; M+ and M- with the double low cell first).

/* host_map.h -- the memory map the host-node tests give the compiler capsule,

|
|
* The node's memory map is open (DECOMPOSITION.md D-4), so the tests choose
|
|
* one. Every test_host_*.c uses this one, so that the capsule's variables
|
|
* and buffers are in the same place in all of them:

* 16 .. the capsule's code, assembled from capsule/ *.v4
|

* DICT_W .. DICT_END_W dictionary space for what is defined at run time
