Some Thoughts re: First hint | Comment 3 of 6 |
(In reply to First hint by Gamer)

Treating each horizontal string as a base-32 number (5-bits in each letter--digits 0 - V) and converting zeros to spaces and ones to asterisks gives:

* ***** * ** *** *
*****         * ***
******  ***  ** ** *
*  *  **   ** *   *

There's some pattern here, but not recognizable.

DATA NQRK
DATA V01E
DATA VJJD

CLS

cv$ = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ"


FOR i = 1 TO 4: READ s$(i): NEXT

FOR i = 1 TO 4
  s1$ = s$(i)
  n = 0
  FOR j = 1 TO 4
   n1 = INSTR(cv$, MID$(s1$, j, 1)) - 1
   n = n * 32 + n1
  NEXT
   b$ = ""
   FOR k = 1 TO 21
    d$ = LTRIM$(STR$(n MOD 2))
    IF d$ = "0" THEN d$ = " ":  ELSE d$ = "*"
    b$ = d$ + b$
    n = n \ 2
   NEXT
   PRINT b$; " ";
  PRINT
NEXT
