I was wondering if  there  was an easy way to determine where the confidence intervals of a line intercept two lines.     Example Below, I’d like to know where the confidence intervals of each line intercept 90 and 110. I'm on SAS 9.04   data data1;       input lot $ age  results ;       datalines;       a 0 100       a 1 101       a 2 102       a 3 101       a 4 99       a 5 101       a 6 100       b 0 102       b 1 99       b 2 104       b 3 95       b 4 98       b 5 97       b 6 104       c 0 104       c 1 99       c 2 97       c 3 102       c 4 98       c 5 100       c 6 101 ;       run;     proc glm data=data1;       class Lot;       model results = lot age*lot/ noint  solution   ;       output out= lsmeans lclm=lclm95  uclm=uclm95   p=p  ;   run;      quit; ...
