Dear Statalist,

it seems to me that I did not understand the Syntax of "foreach", I typed the code below to produce a panel data set for which I had to rename some variables and added an index(1995,1996,1997,...,2004) as suffix. The loop works perfectly well until it reaches the last variable "kzahl". I do not know why but the last variable is not processed in the loop. Has anyone an idea where I made a mistake?
I simulated your problem via the following:

clear
set obs 100
corr2data netto pbleib pbbil01 pbbil02 pbbil03 phrf famstd stell pnat nace psbil hhgr eigen kzahl

local wave = "l m n o p q r s t u"
local vars = "netto pbleib pbbil01 pbbil02 pbbil03 phrf famstd stell pnat nace psbil hhgr eigen kzahl"
local y = 1995

foreach x in `wave' {

foreach z in `vars' {
gen `x'`z' = `z'
rename `x'`z' `z'`y'
}

local y = `y' + 1
}

As far as I can tell, it worked fine. Are you sure that lkzahl, mkzahl, etc. exist?
