CBM DOS filetypes are similar in function to beloved msdos filename extensions, aren't they?

Yet you don't insist on using FOO.EXE for data files instead of e.g. FOO.DAT, do you?

In case of LOADable blocks. Not so much in case of sequential data, read byte by byte and processed in portions. For such cases SEQ was/is the most natural choice.

Why then examples in the books about programming data access using sequential files uses SEQ files? Do you think the authors were stupid?

"Usually" is the secondary key here. And even this is arguable. They are _always_ expected to contain data, though. Arbitrary or not doesn't matter that much.

Once again - PRG files are expected to be LOADed, SEQ files are expected to be read byte by byte, period.
