> thanks for your quick answer. But
I think he actually answered your question. I.e. try it with this
extra 'do' statement:
winSSQ count noRed noBlue = do { do
let yesRed = [1..33] \\ noRed;
let yesBlue = [1..16] \\ noBlue;
bracket (openFile "ssqNum.txt" WriteMode) (hClose) (\hd1 ->
pickSSQ count yesRed yesBlue hd1);
}
In the future please use complete examples that have all variables and
import statements. It helps us help you.
Cheers,
Thomas
