[BioC] rma question

I am trying to run RMA algorithm of more than 256 arrays.  One problem I
encoutered was that the excel file (output file) allows maximal 256 columns.
I then named the output file as "output.csv" or "output.txt".  No one of
them worked for me when more than 256 arrays were processed.  The algorithm
was run but there was no output file.    I ensure that it is not a problem
of any files because as I split the all arrays into two group, each group
could be processed. 

It seems that RMA has a global normalization with all arrays.   If this is
true, how can I preprocess more than 256 arrays with RMA algorithm.
