That referred to this code:

> foreach l of local levels {
>          // next line clears macro
>          local events
>          forval i = 1/3 {
>                  su event`i' if id == `l', meanonly
>                  if r(max) < . local events "`events'`r(max)' "
>          }
>          if "`events'" != "" {
>                  xtline response if id == `l', ///
>                  subtitle(panel `l') xline(`events')

One approach would be something like this 

tokenize "solid dash dot" 

levels id, local(levels)
foreach l of local levels {
           // next line clears macro
           local xlopt 
           forval i = 1/3 {
                   su event`i' if id == `l', meanonly
                   if r(max) < . ///
		local xlopt "`xlopt' xli(`r(max)', lp(``i''))" 
           }
           xtline response if id == `l', /// 
                  subtitle(panel `l') `xlopt' 
           more
}
