Do I have a virus?
Post by KenDown on Sep 1st, 2015, 3:51pm
Something weird has been happening in the last fortnight or so. Programs (*.bbc) that I have worked on as little as the day before come up as "Invalid file format" when I drag them across to BB4W.
I have no idea what the invalid format is, but dragging the file into Notepad seems to show that it has an extra line inserted between the program lines, otherwise the program appears to be OK.
I have written a short routine that reads and discards the first and every second line thereafter, then processes the second and every second line thereafter, by reading in the line and detokenising the BASIC. (Just discarding the excess lines does not seem to work.) Out put to a text file, copy and paste the text file into the BB4W editor and you're back in business.
Has anyone else had this problem? Any ideas what is causing it?
