You got that message and wonder what it means? Here are the instructions which were found in NOTEPAD when you started the program:
=======================================================
QBasic Mac's SuDoku Cheater
x = blank cells
----------------- Puzzle follows ---------
Leave the first three lines unchanged except
replace x with the character you use for blank cells
Then replace all these instructions with your puzzle
What you put here will be scanned and everything will
be ignored except digits 1-9 and whatever you are using
for blank cells.
Required: exactly 81 hits which will be assumed to
be your puzzle
=======================================================
Here is an example of someone following the instructions:
Note that 1) "*" = blanks and 2) all other characters, which were presumably copied from some SuDoku site, are ignored. The only characters honored are *123456789 and there must be exactly 81 of them.
