Mark, I feel its a pretty poor port. I don¡¯t think its been tested properly. The open error code is because its opening a file, we don¡¯t get the name because of the hacks to get PDPCLIB working. Perhaps the PDPCLIB run time needs fixing. Just double up the double quotes. Dave ? ?

Interactive mode seems a bit dodgy. I can use apostrophes (')? for print statements, but it doesn't execute. Use of quotes ("), they just disappear.
