I'm currently implementing file access in my TiVi editor. The editor is designed to run in 80 columns mode.   My question is what text file formats should be supported? I mean DIS/VAR 80 for sure. But are there editors out there that support other file formats as well. Does it make sense to implement scrolling in the editor so that I can let say open a file with 255 record length and show it on a single line with scrolling?   Any opinions on that?
