In SAS, is "not =" a legitimate operator?

I've come across a program that uses not = as if it had the same meaning as ne or ^=. It seems to work fine, and doesn't raise so much as a note to log. But I can't find any official documentation confirming that this is supported syntax.

Is not = really the same as ne?

I see now that this is actually how Enterprise Guide writes its queries when you create a "not equal" filter in a query, using one of the wizards. – Jeff
And now I see that not = is what SAS puts in the log at the end of a data step when you use a subsetting where, whether you use ne or ^=. – Jeff

Yes. Look at the documentation here http://support.sas.com/documentation/cdl/en/lrcon/67885/HTML/default/viewer.htm#p00iah2thp63bmn1lt20esag14lh.htm

data _null_;
x = 1;
if x not = 0 then
    put x=;
run;
