Dear list,

I am trying to loop over all names of variables in the memory. to prepare for that, I want to prepare a local that lists all my variables. I thought that r(varlist) stores them, but, as you see below, the "descibe, simple" commmand gives me all my variables, it stores only a subset in r(varlist).

Does anyone know why that happens?

Thanks for any hint,

daniel



#### from my do-file

describe, simple;
display r(varlist);
local AlleVariablen = r(varlist);
display "Im local AlleVariablen steht: " "`AlleVariablen'";

foreach x of local AlleVariablen {;
codebook `x',compact;
tabulate `x';
};
