Not sure what you mean? What's the bad habit? The idea of using .BA for plaintext BASIC files and .DO for text documents made perfect sense in the old days. Keep in mind that a stock M100 can not transfer binary files such as tokenized BASIC or .CO, so normally all files transferred would be plain ASCII and you would only have tokenized files on the M100 itself.
The problem being discussed only arose once various means of transferring binary files without discriminating between binary and plaintext came along. m On Wed, Mar 1, 2023 at 3:29 PM Peter Vollan <dprogra...@gmail.com> wrote: > See, I take the unpopular opinion that that should not be done because it > teaches bad habits. > > On Wed, 1 Mar 2023 at 06:20, <bir...@soigeneris.com> wrote: > >> I also tried loading a .DO named as .BA through BASIC, i.e. load >> "com:98n1e" and that worked fine.
