Indeed, that does work. I was just suggesting an alternative.

For the moment it works when using K C Wongs suggestion but modified with "`var'" as you suggested.

if "`var'" != "idnr" {
rename  `var'    `k'_`var'

Looking at the question again, the core is 

foreach var of varlist _all { 
	if "`var'" != "idnr" rename `var' `k'_`var' 
}

Picking up an idea from Fernando Rios Avila [f.rios.a@gmail.com], and adding another, this might as well be 

rename (*) (`k'_*) 
rename `k'_idnr idnr 

bearing in mind that in Stata 12 -- which you are presumed to use unless you flag otherwise -- -rename- has a bunch of new features that allow renaming of multiple variables.
