Hi,
I want to run a simple wireless tcl example but I encounter this error:

invalid command name "-llType"
while executing
"-llType $opt(ll) "

what is the problem with it?

Examples copied from e.g. the Internet must often be edited.
One or more <space> after \ must be deleted.

Line distance / a line feed in the middle of a command must be corrected.
.. And invalid characters like “ ” must be edited to " "

Example

thank you so much,knudfl
