st: rename with if

[Tomas Lind <Tomas.Lind@ki.se>]

Hi Statalisters,

I want to rename all my variables (in lots of datasets) except the first variable which is idnr. The problem with the syntax below is that "if is not allowed". 

Someone have a solution to this?

levelsof  atc  ,  local(cat) 
    foreach  k  of local cat {
           preserve 
           use "G:\ATC-dataset_`k'"  ,  clear 
                 foreach  var  of varlist  _all {
	      rename  `var'    `k'_`var'        if `var' != "idnr"     
		          }			
	save "G: \ATC-dataset_`k'" , replace
          restore
	         }
