File type and mode does not seem to work

[rzuckerm]

This creates a file called output.txt, SEQ, W instead of a writable file called output.txt:

10 OPEN 3, 8, 2, "output.txt, SEQ, W"
20 PRINT#3, "Hello from Commodore Basic"
30 PRINT#3, "This is a line"
40 PRINT#3, "This is another line"
50 PRINT#3, "Goodbye!"
60 CLOSE 3

Correspondingly, this cannot be used to read output.txt:

70 OPEN 3, 8, 2, "output.txt, SEQ, R"
80 INPUT#3, $A
90 IF ST <> 0 THEN GOTO 120
100 PRINT A$
110 GOTO 80
120 CLOSE 3

Instead, it tries to read a file called output.txt, SEQ, R.

I found this example. It looks like this differs from the C64 documentation I found on the C64 Wiki. I got this working:

10 OPEN 1, 1, 1, "output.txt"
20 PRINT#1, "Hello from Commodore Basic"
30 PRINT#1, "This is a line"
40 PRINT#1, "This is another line"
50 PRINT#1, "Goodbye!"
60 CLOSE 1
70 OPEN 1, 1, 0, "output.txt"
80 INPUT#1, A$
90 PRINT A$
100 IF ST = 0 THEN GOTO 80
110 CLOSE 1
