Hello,
You've right, flush is included in the close command.
Flushing on a closed file handle brings nothing!
I think it is better to use an update (or update idletime)
command to give the surrounding TCL-system the
chance to write his cache out. This is like a "sync"
under linux or a <F5-Key>  in Windows-File-Explorer.
Greetings, Thomas

	Thanks that did the job, but I think 'close' command should also
flush the buffer.
	accrding to manual for 'close' command "All buffered output is
flushed to the channel's output device". Then why should I use 'flush'
seperatly after 'close':

	    set out2 [open "cabprop.dat" a+]
	    # add some strings
	    close $out2

	    flush $out2
	    # destroy window

		The problem is after the window (the window that
contains "save") has closed, the file content won't get updated. I have
to close the main window and after that the text editor prompts for
reloading the file. I don't know why... 'close' command should close the
file but it doesn't work until the main window is closed.
