Thanks Jacki! It's exactly what I needed! 

Thanks also to Philipp, Nick and Justin for replying to my query.

Juanita,

I could be wrong, but I think reshape allows you to specify where the
'j' portion of the data resides within the variable name using the '@'
symbol.

so, with data as you've described :

> > date  code1_varx     code1_vary   code2_varx  code2_vary
> > 1990        10            20           10          30
> > 1991        10            20           10          30

you could type

     . reshape long code@_varx code@_vary, i(id) j(code)

which should give you

> > date  code_varx     code_vary   code
> > 1990        10            20           1
> > 1990        10            30           2
> > 1991        10            20           1
> > 1991        10            30           2

then you would just have to rename each code_varx to varx to vary, as
follows:

unab codevars : code_*
foreach V of local codevars {
        local rename=subinstr("`V'","code_","",.)
        rename `V' `rename'
}
