ZEROONETwOThReEFOUrFIVeSiXsEVENEIgHTNinE
In the above concatenation of the cardinal numbers zero-to-nine WHERE IS GIN? is spelled by the small letters.

In a similar way , one can select ERRORS, WORSEN, RESIGN, ROOFS etc.

Some tasks for you:
a. Try to create the longest valid word.
b. Try to create the longest sensible question.
c. Forget about the order, using any letters from the available Z-E chain create the longest valid word/sentence.

src$ = LCASE$("ZEROONETwOThReEFOUrFIVeSiXsEVENEIgHTNinE")
CLS
OPEN "\words\words.txt" FOR INPUT AS #1
DO
  LINE INPUT #1, w$
  s$ = src$
  good = 1: p = 1
  FOR i = 1 TO LEN(w$)
    ix = INSTR(p, s$, MID$(w$, i, 1))
    IF ix = 0 THEN good = 0: EXIT FOR
    p = ix + 1
  NEXT
  IF good THEN
    IF LEN(w$) > 8 THEN
      max = LEN(w$)
      PRINT w$, max
    END IF
  END IF
LOOP UNTIL EOF(1)
