S -> SEQ, P -> PRG, U -> USR and there is no difference with using these, except the filetype in the directory is different. (its really just a single byte :)) the internal structure is exactly the same. as said before, it doesnt really matter if you stay in cc65 universe - it matters when you break out and want to create files that other existing programs can deal with (which are in the vast majority prg files) > - What happens if a file already exists?

What do I need to > set '_filetype' to in order to get the previous behaviour? generally i want to answer this question like this: its a bad idea to overwrite a file, you should first delete it (using the dos "scratch" command) and then write it again. if you dont do that you might trigger the "save-with- replace bug" and eventually destroy the disk in the process (ie, lose data) as for the original question - its preserved as far as i know :) > > i would even say that by making it prg, you will 100% > > eliminate any "how do i change the default filetype" questions > > My section above already proves this claim to be wrong on the very first > day! no - for you the question only arises because you - for whatever reason - used a different filetype before. again, it doesnt matter at all inside cc65 world, you can use whatever you want there with no drawbacks at all. -- http://www.hitmen-console.org http://magicdisk.untergrund.net http://www.pokefinder.org http://ftp.pokefinder.org Man kann auch saufen statt rumweinen.
