I read the fine prints more than other parts and I clearly remember this was somewhere in docs, maybe KB. Unfortunately I can't locate it once more. Personally blindly thinking it's true as I remember it was coming from fox team with a test showing the case. Till I can prove wrong myself I believe it (personally:)

Cetin,
Do you remember if it was the m. in the body of the loop or the loop itself that was the issue?
for m.ln1 = 1 to 10
  .....
endfor

or 

for ln1 = 1 to 10
  m.ln2 .....
endfor
