Dear Kit and Joseph,
Thank you very much for suggestions. I tried the way of Kit
local one=string(xx)
local two=string(yy)
local both `one'`two'
and it works, but I am a beginner in Stata and I don't know how to
use -file- command. I tried, but without results. I need to put `both' into
an ASCII file. Could you please write the command literal?
Thank you in advance,
Lilian
