Re: [Jprogramming] Yahoo stock quotes

Ric for not looking at my code you are amazing. I put the ‘dquote’ function in front of the URL that goes to get the actual stock quotes and bingo CSV data dumped into my Jqt screen. It’s the second to last line of my script that was the culprit. It initially was: res2 =: '-s -b cookie.txt ' g

Hi Jimmy (sorry, been away for 3 days), good question and we have investigated FPGAs, but abandoned for these reasons: We prefer “vanilla” code in the engine (less dependencies, don’t tweak the Linux kernel, minimal external packages and libraries etc) We also code-generate from a very general ER
