...
Well, to put it correctly, the text string is not converted into a list, but inserted as a single list element into a list.

Simply put, the string "This Test" becomes "{This Test}", and [lindex "{This Test}" 0] returns the first list item being the string "This Test".

ahh.. ok.
Very clear.

Thank you.

And I'm sure this will all help the original poster, when he returns.

So when this bind that normally passes a text string does so, and hits the parameter named args in that place, it is converted on-the-fly from a string to a list?

...
With that said, for those stumbling into this thread in search for information regarding list errors...
First of all, $args is actually a list.

This is why I never use it, unless I mean to use it - and that is very rare.

I hate to see it, but I forced myself to leave it, since that is what it was originally. To change it, I would have had to explain why I changed it....
ugg...

The reason is that having the last parameter in a proc declaration being named "args" makes it behave like varargs in other languages; that is, accept multiple number of arguments. Each argument will be added as a list item to $args.
Splitting $args makes absolutely no sense here.

Ok.. I didn't stop and even think about it at the time. I just forced myself to go with his naming.
Thanks.

Be advised that we do not support piracy, and torrents tend to be synonymous with piracy these days:
From forum rules:

No requesting help on anything involving "piracy" (of software, movies, or otherwise), because it's illegal in most places.

In virtually all cases I've seen, the first fault is that people use the name "args" without knowing it's special properties.
The second fault is that they "solve" it by using lindex to extract the first item, without actually knowing why they are doing it in the first place...

Code:

return [isy:createtorrent $nick $host $hand $chan $arg]

I guess that
isy:createtorrent
is some proc that you have elsewhere. We haven't seen what is in it.
We have to hope that it doesn't have errors in it.

I don't know about having the result returned by the return command being the return of yet another proc. Maybe Spike knows if that is do-able.

What are you trying to do though? ... Why is the return command used like that?

I ask, because I'm wondering if you just want to run that other proc while passing those parameters to it.
If so, forget the use of the return command.
Just :

Code:

isy:createtorrent $nick $host $hand $chan $arg

Think of
isy:createtorrent
as a new TCL command that you have created, and just use it.
(this assumes that it is a proc that is already loaded)

About just what we are are talking about above.

Also has help on using timers.

TCL error

2016-09-29T13:39:57-04:00

Code:

set arg [lindex [lindex $args 0]]

$args is a string.
lindex works on lists.
You can "get away with it" sometimes, but it is not the right way to go about it.

Convert the string to a list, using
split

See: http://www.tcl.tk/man/tcl8.6/TclCmd/split.htm

Code:

set arg [lindex [split $args] 0]

if you want to get the first word in $args

I hope this helps.

Problem's probably here...

Code:

set arg [lindex [lindex $args 0]]

Why do we lindex twice??
