Hey.
How can I split a variable or peramiter, that contains more than one word, into different sections?
ex.
set testvar "word1 word2"
how could I get what the first word is and what the second word is from the variable?
do I have to put them into a list and use lindex or somthing?

getting different words/splitting variables up into differen
Yes and no.
Taking your example, to get the second word from the string, you can use the follwing.
The lindex command is used to get an item out of a list. You have to pass it the list, and the item number you want from the list. The split command is used to convert a string into a list (this is also required to make things safe for later). The 1 is the index within the list that you wish to get. Note the index is 1, but the word we want is word 2, this is because, like in most languages, the first eliment is 0.

OK, so the "set word you can undertsand.set word [lindex [split $testvar] 1]

kewl that works...
another problem (I've seen you give that answer to a previous post about names with { } in them.....
is there a way of removing characters? e.g those { } ones...
I'd assume it would envolve finding the position of the character and then doing somthing to replace it?
I couldn't really figure it out yesterday, could anyone shed some light? ta

K, Having a problem using it.... maybe you could clear it up, or will I HAVE to remove the { for this to work?
using a bind to
bind msg - test handletest
proc handletest { nick host hand args } {
#shows what the output is
putlog "hand [lindex [split $args] 0]"
if {[validuser [lindex [split $args] 0]]} {
puthelp "NOTICE $nick :your handle is ok"
}
return 0
}
/msg bot test HANDLE
works fine, problem is...
/msg bot test HANDLE <anything else here>
returns {handle - thus causing the error and not checking right, so have I got the syntax of the check wrong, or am I going to have to remove the { } brackets?
