The #while loop alone should work out okay. Just exampling below:

#declare S1 = 0  //use as many as you need of these to use on Spiral
#declare S2 = 1  //etcetera
#declare C = 0
#while (Count < 9)  //same as FOR i = 1 to 9
//put Spiral code here or use the inc file, with all the loop
manipulated parts
#declare S3 = S1+C  //whatever.
#declare C = C + 1 //or whatever. clock based value, anything...reaching
9
#include "Spiral.inc"  //alternatively use this
#end  //NEXT until loop reaches 9
