There must be a diagnostic message saying that some filed is missing
in the csv file. I detected that only to-day morning.
In your csv file there are three fields named LIN, COL, VAL (btw,
spaces between fields are *not* ignored, so you should remove them).
However, in the table statement:
table ti IN 'CSV' 'sudoku_in.csv' :
fields <- [COL, LIN], givens;
you did not specify a field name for givens (by default the field
name is the same as the name of corresponding parameter). The correct
statement might look like follows:
table ti IN 'CSV' 'sudoku_in.csv' :
fields <- [COL, LIN], givens ~ VAL;
Please see the example I've just posted to the list.
