length of a variable

Hi all,

I have a question.
Let's say I have a variable that outputs news posts.
But I only want to display the first 40 characters + "..."

example:
sifhkshsdlgksdg;lsfgjewpogjeposdopbnkhfsidfhsifoswiofsnfoiansfioan

must become:
sifhkshsdlgksdg;lsfgjewpogjepos...

or something like that.

can someone help me?

I've searched in the forum for something like this, but could not find anything.

thx

Chrizz

It's simple.. I have a line let's call it myline formed this "qwertyuiopasdfghjklzxcvbnm" .. this in tcl will be set myline "qwertyuiopasdfghjklzxcvbnm". Now I want to get from that line a range of characters from 0 to let's say 10, then I'll use "string range $myline 0 10" and I'll get as an result "qwertyuiopa"
