I'm using the superpatch 3.1e with pov 3.1g.

I cannot normalize a 4d vector.  Is  there a bug or am I doing something
wrong?

#declare RRR=seed(2022) ;
#declare UMAX=1 ;
#declare
actorp[n]=UMAX*<rand(RRR)-0.5,rand(RRR)-0.5,rand(RRR)-0.5,rand(RRR)-0.5>;

#declare actorv[n]=vnormalize(actorp[n]);

Also, I'm getting some messages occasionally (after using the patch for
all of 5 minutes)  when trying to #write a 2d vector

#write
(MyFile2,"{",actorp[n].x,",",actorp[n].y,",",0,",",actorv[n].x,",",actorv[n].y,",",0,"}",",","\n")

It hung up at the "y", saying that it was a bad descriptor, or
something.  It didn't like a u & v setup either.  But then this problem
went away!!
