From: Keith on 10 Apr 2010 22:04 I have an array with multiple entries and I am wondering what would be the correct & best way to sort them. $foo(arr,1)...$foo(arr,99) Is there a way to use lsort on all the different items in the array? -- Best Regards, Keith http://home.comcast.net/~kilowattradio/ I'm Your Huckle Berry http://www.youtube.com/watch?v=KfbAFgD2mLo

What do you want sorted the keys or the values? -- +------------------------------------------------------------------------+ | Gerald W.

I want to sort the values in the arrays. $foo(arr,1) = "C wordone" $foo(arr,2) = "A wordone"

So ditch the array and use a list to begin with like this: % set mylist {{arr,1 "C wordone"} {arr,2 "A wordone"}} then use [lsort] % lsort -index 1 $mylist {arr,2 "A wordone"} {arr,1 "C wordone"}
