And generally are supposed to be LOADed, even if they happen not to be executables.

Which are supposed to be read sequentially.

IMHO it doesn't. But it needs the file to be stored on disk somehow. And we talk about how to store the file on disk.

He can do it always. The question was/is (?) what to use if the user does not specify the filetype. In other words whether to force it to be USR as it was before or leave it as SEQ or to switch to PRG as one person strongly advocates ;-)

Some demos, games, some utilities. Programs that want to LOAD the content of their files in one shot.

As final output, yes. But editors for those assemblers and compilers - not necessarily. True - some did. Some not.

You meant PRG files, didn't you? ;-)
