```Well, NCL index values are 1-based.  so a range of 0-to-11 represent 12
values.

Perhaps:
VRH(i:i+12,j:j+12)=k
Should be
VRH(i:i+11j:j+11)=k

====
You might get a lot of print put but you could debug yourself:

k=k+1

i12 = i+12

j12 = j+12

print("debug: k="+k+" i="+i+"  i12="+i12+" j="+j+"
j12="+j12)

VRH(i:i+12,j:j+12)=k
