String Manipulations

What is the best method to replace the second character in a variable string to a last character?

Example

From : XZ94363459445

To: X94363459445Z

This would be my way of doing this:

Code:

set test “XZ94363459445”
set result “[string range $test 0 0][string range $test 2 end][string range $test 1 1]”

C’mon Max, how about a regular expression:   😀

regsub — {(w)(w)(.*$)} test {132} result

or (two commands instead of three)

set result [string replace “$test[string index $test 1]” 1 1]

Just making the point that there are many ways to accomplish the same thing.  I can’t really say one way is better than the other   😉
