Python really writes '\n\r' on Windows. Just check the files.
That's backwards. '\r\n' on Windows, IF you omit the b in the mode when
creating the file.
Indeed! My mistake just made me find out that Acorn used that inversion on
Acorn MOS.
According to this[1] (at page 449) the OSNEWL routine outputs '\n\r'.
What the hell those guys were thinking??? :p
Doing it that way saved a few bytes.
Code was something like this:
FFE3 .OSASCI CMP #&0D
FFE5 BNE OSWRCH
FFE7 .OSNEWL LDA #&0A
FFE9 JSR OSWRCH
FFEC LDA #&0D
FFEE .OSWRCH ...
This means that the contents of the accumulator would always be
preserved by a call to OSASCI.
"OSNEWL
This call issues an LF CR (line feed, carriage return) to the currently selected
output stream. The routine is entered at &FFE7."
