I thought sysopen can't be mixes with print/read, as buffered IO and unbuffered cannot be mixed? And I mentioned that I don't want to use syswrite

Or sysopen is not about unbuffered IO (in opposite to syswrite) ?

(Note that your code still unconditionally truncates the file each time.)
Ok, could you please example why? First file open mode is append, and second is read (read/write)
