st: problem with a list returned by stata (r(varlist))

[Val�rie Orozco <Valerie.Orozco@toulouse.inra.fr>]

Hello,

What I want to do is to store lists (in a macro) of some variables in my 
data.
I use the command "ds" to have them and I thought that thanks to the 
return list r(varlist) I would be able to play with this in my program 
(make some differences and others manipulations of macrolists)...but ir 
doesn't work...

My example is the following :

ds Vol*      /*I want Stata to show me all the variables beginning by 
"Vol" in my data*/
local liste1 `r(varlist)'   /*I put it in a local list*/
di "`liste1'"          /*to test it : it woks*/
local liste1bis `"`liste1'"'  
di `liste1bis'         /*and it is a funny result*/

ds Vol*
VolBR4_seg0   VolBR1        VolBR5        VolBR9        VolMN3        
VolMR5        VolS01MN1    VolS01MN5
Vol0BR4_seg0  VolBR2        VolBR6        VolMN1        VolMN5        
VolMR3        VolS01MN2     VolS01BR4
VolBR4_seg1   VolBR3        VolBR7        VolMN2        VolMR1        
VolMR4        VolS01MN3
Vol0BR4_seg1  VolBR4        VolBR8        VolMN4        VolMR2        
Volmois       VolS01MN4

. local liste1 `r(varlist)'

. di "`liste1'"
VolBR4_seg0 Vol0BR4_seg0 VolBR4_seg1 Vol0BR4_seg1 VolBR1 VolBR2 VolBR3 
VolBR4 VolBR5 VolBR6 VolBR7 VolBR8 VolBR9 VolMN1
>  VolMN2 VolMN4 VolMN3 VolMN5 VolMR1 VolMR2 VolMR5 VolMR3 VolMR4 
Volmois VolS01MN1 VolS01MN2 VolS01MN3 VolS01MN4 VolS0
> 1MN5 VolS01BR4

. local liste1bis `"`liste1'"'

. di `liste1bis'
133008.88133008.8850295.1650295.1621709.86553108.0783532.6653183304.05706.5600625242.53178350.60974817.94556640.7429417

It seems that strings in a list returned by the "return list" command 
are coded...very stranged, isn't it?
If someone has an idea...

thank you very much for trying to help me
