Hey Vad,

from the ImageJ documentation at
http://rsb.info.nih.gov/ij/developer/macro/macros.html#loops:

> the loop.
So the macro language does not support multiple initialization
statements in one loop. You'll have to work around it per your
suggestion or move to another language (see http://imagej.net/Scripting
for example).

All the best,
Stefan
