Hello List, I would like to be able to automagically submit a form to a server. The server requires that I give it a sequence of letters (a protein) in one box, my email, and select several radio buttons to my chosen output. In this case the server is PSIPRED protein structure prediction server

open file for read and append

Hello, I have a script where I need to open a file, read from it sequentially, and append items to the file as I go along, continuing to read these items as I go. But seems I can't open the file for read and append at the same time. Does anyone have any ideas? Many thanks. -- Daniel Klose PhD
