New line when writing to a text file using fprintf?

I would like to print to a .scad file to create a drawing on openscad.

I want to iterate the drawing through 1-8281. However, I want there to be 8282 seperate lines of code. For each seperate segment of drawing. For example, I want the code to print out:

1stline: $fn = 30

2ndline: {translate([1st,1st,0]);cylinder(1st,1st,1st);}

3rdline: {translate([2nd,2nd,0]);cylinder(2nd,2nd,2nd);}

4thline: {translate([3rd,3rd,0]);cylinder(3rd,3rd,3rd);}

…

8282ndline: {translate([8281st,8281st,0]);cylinder(8281st,8281st,8281st);}

i have attached my code here:

xm,ym,l2 and r2 are all 1x8281 arrays which i wish for their ith value to be printed out.

fo = fopen('random_lens.scad','wt')
fprintf(fo,'$fn = 30;');
for i=1:8281
    fprintf(fo,'{translate([%d,%d,0]);cylinder(%d,%d,%d);}',xm(i),ym(i),l2(i),r2(i),r2(i));
end
fclose(fo);

The newline character for fprintf and its friends is '\n', so perhaps:

fprintf(fo,'{translate([%d,%d,0]);cylinder(%d,%d,%d);}\n',xm(i),ym(i),l2(i),r2(i),r2(i));

.
