This is explained here:
http://www.ncl.ucar.edu/Document/Manuals/Ref_Manual/NclStatements.shtml
Search for: "The local statement and function and procedure scope"

Those functions which do not have local variables declared, are probably
for the few functions which do Not define anything new within the
function, i.e., there is No "x=" within the function (hopefully).
