A program I wrote for blassic on another system works with bwbasic on debian. However with yabasic, the input statement throws an error and the syntax is correct for yabasic too. One possibility may be the file suffix since it's now .bas and may need to be changed to yab. The file I wrote the program won't even load in yabasic for editing either. I think the yabasic version is way outdated too so that could be a problem too.
