I guess that your line
local AlleVariablen = r(varlist)
evaluated, not copied. Thus the limit on
the length of a string in a string expression
(see -help limits-) bit you.
Actually, I am a bit puzzled, as in my version
of Stata, 9.2, -describe, simple- does not leave behind
r(varlist) -- contrary to [D] describe and your example.
Anyway, your code can be slimmed down to cut the
middle macro:
ds
foreach x of var * {
codebook `x', compact
tabulate `x'
}
