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?
