Fixed the border between 89 and 104 that was mirrored compared to OP's reference (-1)
Changed declarations of char pointers, added `u=U+1` into start of f() (-4)
Changed declaration of S from `S[]="  "` to `S[4]` (-4)
Changed R10:C701 from `P"____"` to `P u+1` (-2)
Rearranged declarations of char pointers, removing the need for a space (-1)
Changed A() to A(F)P a>9?"|%4d ":"|%3d  ",a);} (-22)
Changed e() to only fetch the next element, making possible one fewer arguments to it. Recquired rearranging `l` (-41)
This allows B() (now `B(n){for(;n--;)b(e(S));}`)to only reqcuire one argument as well (-33)
Only A using F now, so remove that define (-12)
