documentation of the BSPLINE function

Greetings!

Has anyone noticed a possible typo in the documentation for the BSPLINE function in SAS/IML?

Under the argument definitions,

"i is an optional argument that specifies the number of interior knots when n=1 and k contains a missing value."

Then goes on to to define the interior knot placement as a function of k, which is a missing value.

What am I missing, here?

Thanks in advance!

Maybe I am looking at the wrong sentence, but the latest documentation saysm

is an optional argument that specifies the number of interior knots. This argument is used only when k is a scalar that contains a missing value.

A HA!!!

I'm working from the documentation for 14.1, which defines the interior knot placement in terms of k.

My guess is that this is a typo in the 14.1 documentation.

Thanks!
