什么意思啊
楼主
解释一下

*机械插值
loc w x1 x2 x3 x4 x5 x6
token `w'
loc w `1' `2' age `3' `4' age `5' `6'

*w包含偶数（且>2）个words，每隔两个words插入word"age"，且两端不含"age"
loc w x1 x2 x3 x4 x5 x6 x7 x8 x9 x10
token `w'
loc n=wordcount("`w'")-1
forv i=1(2)`n'{
loc j=`i'+1
loc t="`t' ``i'' ``j'' age"
}
loc t=substr("`t'",1,length("`t'")-4)

这样做有何意义？
