I'm still learning tcl and am playing around with the wish shell writing interactive tcl commands/scripts. This is all going fine except for one thing. I'm using tcl lists and the lreplace command that replaces elements in a list, syntax: lreplace list first last when this command is run the command line appears to confirm the relevant list element replacement. However, when I run the set command on the list (or puts) to reconfirm that the contents of the list have changed - the list is displayed unchanged. Why is this?

I'm still learning tcl and am playing around with the wish shell writing
interactive tcl commands/scripts. This is all going fine except for one
thing. I'm using tcl lists and the lreplace command that replaces elements in
a list, syntax:

   lreplace list first last <args>

when this command is run the command line appears to confirm the relevant
list element replacement. However, when I run the set command on the list (or
puts) to reconfirm that the contents of the list have changed - the list is
displayed unchanged.

Why is this? I've checked Ousterhout's book and can't see what I'm doing
wrong.

Thanks,
