Raul, Your script for parsing the printed grid looks very effective, but I could not find an example html page at https://www.sudoku-puzzles-online.com/ to try it with.
Instead I found a page like the following one and simply selected/highlighted the grid from the screen and copy-pasted that into vim. Then I globally replaced tab characters with null characters using :%s/^I//g and got usable text. This is not very j-like, but it worked in a pinch. https://www.sudoku-puzzles-online.com/cgi-bin/hexadoku/print-1-grid-hexadoku.cgi ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
