you can stack as many else-if as you want:
if max(a)<20 then p=0;
else if max(a)<30 then p=0.5;
else p=1;
this eventually leads to wallpaper code;
better to use a format
proc format max 0-20 = 0
21-30 = 0.5
31-hi = 1;
Data X;
*...;
p = put(Max(A),max.);
also consider the alternate case structure;
maxA = max(a);
select(maxA);
when(<20) p=0;
when(<30) p=0.5;
otherwise p=1;end;
