What is going on here has to do with the way -di- works. If you type
-di varlist- it will diplay the values of the first observations of the
variables in varlist. The local `list1bis' contains a string with
variable names separated by spaces (a list). If you type
-di variable list. So, if you type: -di `listbis'- Stata sees
-di varlist- and it displays the first observations of each variable
in the varlist. To see the names of the variables in `list1bis' type:
-di "`list1bis'".
Hope this helps,
