Hi,

please help me understand the following

the symbol -< , <- and <-< are confusing

%let big=0.7;
proc format;
    picture correlations &big -< 1 = '009.99' (prefix="*")
                         -1 <- -&big = '009.99' (prefix="*")
                         -&big <-< &big = '009.99';
run;

Hi @hqquenafees

By default, a simple hyphen (-) means that boundaries are included.

To exclude them, you can use the inferior sign: <

&big -< 1 = '009.99' (prefix="*") is equivalent to [&big;1[
-1 <- -&big = '009.99' (prefix="*") is equivalent to ]-1;-&big]
-&big <-< &big = '009.99' is equivalent to ]-&big;&big[
