VIM add interval annotation correctly

fun!Jzsqj() range
"\ Annotated interval , You can't ."
"\ Find matching comments "
let z=Qzss()
let z="'<,'>norm I" . z
" such , no way , Make mistakes "
exe z
" Add... To each let"
norm ^[
" sign out esc"
endf

Changed to the following :

fun!Jzs()range
" Annotated interval let i=0;jjI Comment string <esc>"
let z=Qzss()
let k=Schs()
"z Comment string of type ,k Is the row difference of the visible interval ."
norm 0;
let s:ss='norm! {}jI{}'
" First select the interval , Again I Add the content , Last esc"
let m=Thgs(s:ss,k,z)
exe m
norm ^[
endf
