Note that
if condition1
%do first thing
else condition2
%do second thing
end
is really the same thing as
if condition1
%do first thing
else
condition2
%do second thing
end
You might perhaps have wanted
if condition1
%do first thing
elseif condition2
%do second thing
end
However we suggest that you only use this form if there is some possibility that neither condition1 nor condition2 are true. If condition2 is intended to catch all of the cases in which condition1 fails, then you should just use else
if condition1
%do first thing
else
%do second thing
end
There is a way in which both of your conditions could be false: if either TempMax or TempMin were nan, then TempMax >= TempMin and TempMax <= TempMin could both be false.
