SDL will do what you want (3.2.2.3  File I/O Directives)

basically you need to create a file for input (#fopen)
then write a text string in your loop corresponding to the scene file
operation.

eg:

//start
#fopen OutFile1 "LoopOutput.txt" write

#local RND=seed(1);
#local i=0; #while (i<10)
   #local j=0; #while (j<10)
      #local k=0; #while (k<10)
         #local Rad=rand(RND)*0.5;
         sphere {<i,j,k>, Rad pigment{rgb 1}}
         #write(OutFile1,"sphere { ",<i,j,k>", ",Rad," pigment{rgb 1}}n")
      #local k=k+1; #end
   #local j=j+1; #end
#local i=i+1; #end

#fclose OutFile1

//end
