; ILT - insensitive lookup table. A-Z/a-z are
; the same. this increases processing speed by
; many times. example: if (tt[a]=tt[b]) instead
; of: if ((a>='a'&a<='z')&(b>='a'&b<='z')) |
; ((a>='A'&a<='Z')&(b>='Z'&b<='Z'))

; TLT - type lookup table. each byte contains
; C.X BITs to determine its type fast in one
; comparison. example: if tt[c]&SYMBOL
