Rich,

sncross doesn't support any arbitrary text positioning or labeling,
but I dug out an old contrib program called gptext that you can use
to do the job.

I posted this in ~gbuddy/nawips-5.4/contrib/gptext.tar.Z

Download into $NAWIPS and unpack/install with:

zcat gptext.tar.Z | tar xvf -
cd gempak5.4/source/programs/gp/gptext
make 
make install
make clean

Once the program is installed, you can write text (and rotate) such as:
TITLE    = 5//Height (m)                                                        
   
TEXT     = 1/21/1/sw                                                            
   
POSITION = .03;.45;90                                                           
    
DEVICE   = XW                                                                   
   
COORD    = n
gptext->r


This will write the title string (in color 5) in the device normal
coordinate system (0->1 screen coordinates) at position X=.03 Y=.45
and rotated 90 degrees. It might take a few tests to get the X/Y location
figured out for your plot, but after that it should be easy.

Online help will be available for more information as well.
