Thanks Ed for the precisions
  I'm not dealing often with feets!  Sorry!

Jim / Skweda -

No, in this case you DON'T want to put UNITS METERS in the layer section,
because these units are not meters.  The PRJ file indicates that this is a
State Plane projection with units of US Feet.

UNITS DD in the main MAP file section is a good idea, however - it's not the
cause of this problem, but it will prevent other problems in the future.

Be sure to put UNITS DD in the map section and UNITS METERS in the layer
section since LCC is in meters...

I'm trying to plot a property parcel shp file, and it keeps plotting in
Pennsylvania instead of North Carolina.   

It also prints out the wrong size.  (much to big ) 

I've posted my parcel layer (from the .map file )  and the PRJ file that
came with the shp file. 

What am I doing wrong ? 

My map file output projection is :

PROJECTION

  "proj=longlat"

  "ellps=WGS84"  

END

Thanks !

Jim
