Not so weird.
First, is -norm()- documented as a function in your version of
Stata? You should have checked that out first.
Second, -norm()- used to be part of Stata, and it's still there
under version control.
. version 9 : di norm(.6)
.72574688
. di normal(.6)
.72574688
There is a slow shift towards more meaningful function names in
Stata. If do-files and programs declare a -version-, as programmers
are clearly advised, then nothing will be broken.

Also, see -help whatsnew8to9- and search for "The following existing
functions have been renamed". The renaming actually occurred in
version 9 but the old names continued to work without version control
until Stata 10, I believe.
I love the way old commands and syntax continue to work under version
control. However, finding the documentation for outdated commands can
be a hassle at times. I have every version of Stata from 7 on, partly
so I can track down the help for now-outdated and undocumented syntax.
