(open "myfile" "a") doesn't work as expe

[gregben]

The following code:

Code: Select all

(device (open "myfile" "a"))
(print "This goes in myfile")
(close (device))
(exit)

fails with: value expected : (open "myfile" "a")

when the file "myfile" doesn't exist.
If you use (on Unix):

#touch myfile

And rerun the code above, it works as expected.

I would expect that a file opened for appending with "a"
or "append" would not require preexistence of the
file to start writing to it. This is the common usage,
at least on Unix systems.

I agree, added an O_CREAT flag to append mode in version 8.5.5
