RE: [Repast-interest] ObjectDataRecorder

[Richard T. <ric...@ya...>]

Dear Nick,

Thanks for your advice.
Please can you give me an example of how to use the
DataRecorder in this way to record strings? I can't
quite figure out how this could be done.

Am I right in thinking that the difference between
ObjectDataRecorder and DataRecorder is a matter of
programming style? As well as the block headers!

To Meredith: the sed script sounds a great suggestion.
I would like to have a look at that.

Thanks,

Richard
