Have you tried something like

f = fopen ("data.txt");
nvar = 4;
for i = 1:nvar
   [var x y z] = fscanf (f,"%s %d %d %d","C")
   eval (sprintf ("%s = %d", var, z))
endfor

Where data.txt is your file (you have remove the "-----------------")
and nvar is the number of variables you want to read.
You can improve from here, I guess.
