What emerges from this design is something resembling a tiny virtual machine built on top of TeX’s macro expansion engine. The \count registers serve as RAM (with dedicated address ranges for the board (200-263), scratch computation (188-194), and the search call stack (10000+)). The \csname lookup tables act as a read-only ROM for precomputed data (file/rank mappings, piece-square tables, material values). Token lists (\movelist, \legalmovelist) serve as dynamically allocated buffers. Macros like \makemove/\unmakemove and \pushstate/\popstate are the instruction set. TeX’s \ifnum and \loop primitives provide the control flow. The whole thing is a register machine with no stack frames, no heap, and no garbage collector (just flat integer registers and name-based indirection). pdflatex is, in effect, the CPU executing this VM.

Prices for veterinary services differ vastly across the UK. Clear Vet's analysis of more than 500 practices found that an out‑of‑hours emergency consultation costs an average of £209 nationwide, but the figure drops to £142 in Yorkshire and rises to £295 in Manchester.
