Thanks Nick. My error was in thinking that the forval 1/3 would loop over the variables, and at each loop would clear/replace the contents of -local events-

The mkmat thought was incomplete, I had been trying to work through this for a fair time before I posted to the list the first time, and had thought that perhaps I could make a matrix from the three variables, and then read a row into a macro. I did not pursue it further, so I'll leave it there for today.

Thanks again for the explanation


No. You should get up to 3 lines, by virtue of the
-forvalues- loop. Here's the code again:

levels id, local(levels)
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')
         else xtline response if id == `l', subtitle(panel `l')

The -forvalues- loop loops over -event1- to -event3-.
Of course, your variable names may well be something else,
and may not have such structure.
