I'm trying to #read an array of vectors.

This is odd, but the first row reads OK, but the second row reads the "x" as a float,
and then barfs with a...

Attempted to redefine a vector identifier as a float identifier.

heres the code...

#if (file_exists(datafile) )
    #debug "FILE EXISTS\n"
//read DATAFILE
   #fopen MyFile datafile read

   #declare i=0;
   #while (i<ballcount)
     #declare loc=<0,0,0>;
     #declare vel=<0,0,0>;
     #declare col=<0,0,0>;

     #debug concat(" reading ",str(i,5,0),"\n")
     #read(MyFile, loc,vel,col)

     #debug "\nLOCATION  "
     #debug vstr(3, loc, ",", 0,1)
     #debug " VELOCITY "
     #debug vstr(3, vel, ",", 0,1)
     #debug " COLOR    "
     #debug vstr(3, col, ",", 0,1)
     #debug "\n"



     #declare locations[i]=loc;
     #declare velocities[i]=vel;
     #declare colors[i]=col;


     #declare i=i+1;
   #end

   #fclose MyFile


#else


---------
here's the first 2 lines of data...

...and here's the debug stream.

Never mind I got it... I need a comma at the end of each line in the data file.
