Ok.That explains we need to wrap `r(varlist)' with " " to display the strings. However, 
sysuse auto
ds 
di r(varlist) shouldn't have given     make price mpg rep78 headroom trunk weight length turn displacement gear_ratio foreign
for eg. 
local x "Make"   // x is a macro
di a   
a not found

di a doesn't work but di r(varlist) works although both a and r(varlist) are macros. Please explain. 

Thanks, 
Tashi
