最近在学stata编程，编了以下程序
local count 0
local country US UK DE FR
foreach c of local country {
  local count =‘count+1’+1
  local newlist "‘newlist’ ‘count’ ‘c’"
  }
display " ’newlist‘ “
可结果为
. local count 0
. local country US UK DE FR
. foreach c of local country {
  2.   local count=‘count+1’+1
  3.   local newlist "‘newlist’ ‘count’ ‘c’"
  4.   }
‘count invalid name
r(198);
end of do-fille
正确结果应为
1 US 2 UK 3 DE 4 FR
错在哪里？    请大虾们多指点。不胜感激！
