Amanda,

it seems your problem is to create a list of the variable-stubs you
want to -reshape-. There might be better alternatives but drawing on
what you have so far, here is something that should work

forv j = 1/20 {
    unab add : *`j'
    loc add : subinstr loc add "`j'" "" ,all
    loc stubs `stubs' `add'
}
loc stubs : list uniq stubs

reshape long `stubs' ,i(id) j(wave)

Best
Daniel

I
would like to reshape the whole data sets into long , not just a few
variables.

What I tried is:
------------------------------------------------------
unab var: *1
local stubs: subinstr local vars "1" "",all
reshape long `stubs',i(id) j(wave)
-----------------------------------------------------
 This causes problems for the variables that are not first created at
wave 1. However, if I use 20 instead of 1, I got similar problem for
those variables that are stopped being collected before wave 20.
