They are both part of metadata of the file. They both suggest what the content may be. They both suggest what you might do with the file.

We are on the very same page! That's why I wrote "beloved" ;-) Yet this utter stupidity is with us for long and not only it seems to be there to stay but moreover it already infected or is further infecting systems, which were previously immune to this form of stupidity.

Yet I don't recall any of them saying "don't use SEQ for anything else than textual data". It is rather just plain natural to use SEQ when it comes to sequential DATA. Which is BTW the same what CBM DOS does when opening file for writing with appropriate secondary address! I admit that for a long moment I was fooled by your argument that "BASIC creates PRG by default". This is not true as Andre pointed out. It happens only when you use channel# 1 (aka sec addr 1), using which is against the rules set in 1541 manual for example: FORMAT FOR OPENING A SEQUENTIAL FILE: OPEN file#, device#, channel#, "0:name,type,direction" [...] The channel# is a data channel, number 2 through 14 [...] Which IMHO takes away the only valid point I thought you had but - OK - seems that we keep having different opinions on this matter. -- SD! ---------------------------------------------------------------------- To unsubscribe from the list send mail to majordomo@musoftware.de with the string "unsubscribe cc65" in the body(!) of the mail.Received on Sat Jul 7 11:48:48 2012
