Multiple initializations in a for loop

[ved sharma]

Hi all,

I received an error when I tried to have multiple initializations in a for loop. Does macro language not support multiple initializations?

Here is the macro I was trying:

for(i=2, str="1"; i<=5; i++)
        str = str+","+toString(i);
print(str);

The macro works fine (prints 1,2,3,4,5), if I pull one of the initializations (str="1") out of the for loop.

Thanks!

Ved

Hey Vad,

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

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
