Yes, but 'Pos is not defined for all scalar types, so of
course you do not see it there, instead look for attributes
of discrete types and you will find it in RM 3.5.5.

But a little higher level advice, you definitely need to
improve your skills in finding things in the RM. Two
suggestions:

1. If you have a paper copy (or an electronic copy), use
the index. That is what it is there for! The index is quite
complete, and there is an entry for Pos that points to
3.5.5.

2. Get an electronic copy. There are HTML versions around,
but I prefer a straight ASCII version easily searched in
any editor, and then just search for Pos.
