Sorting Array?

Hi:

New to TCL here and I'm trying the following:

array set lang {0 undefined 1 critical 2 major 3 minor 4 informational
5 ok 81 debug}
#
foreach key [lsort -index 0 [array get lang]] {
puts "$key : $lang($key)"
}


I know that with a hash table I won't get the order out 0, 1, 2, etc..
so I'm sorting first,
however, obviously I'm not doing this correctly because I get:

can't read "lang(critical)": no such element in array
while executing

Which tells me I'm really not doing a key,value pair here. Could
someone point me in the right direction.

Thanks
Tom
