Writing to a text file

[Guest_imported]

I know this has been answered before but, what I'm trying to do is a little funny (well to me the newbie tcl coder!).

This is what I've got:
set loc d:/

button .framemid.ok -text OK -command { .framelower.result config -text [.framemid.location get]
set output [open hds w]
puts $output $loc
close $output}

When I run this I get the error:
can't read "output" no such variable

Any ideas what I'm doing wrong?

Thanks

Looks like the

[open hds w]

got an error. Maybe the file "hds" can't be created for some rights reason.
If this is true, you should get an error. I suppose that you can't see it because your script is registered inside the button command.
To trap the generated error try to define a bgerror proc:

proc bgerror {msg} { tk_message -message $msg }

Good luck.
