Thread: How to open, write data to and close a new file for each step of a loop.

Hi everyone,

I'm having a problem with a program I'm writing. I'm doing a numerical simulation, and as part of the simulation, I need to output a data file for every timestep, or later output the data of ten timesteps to a data file etc.

The problem is that I would like to be able to vary the filename in each iteration of the loop in a counter fashon.

For example data 1.dat
data 2.dat
and so on.

I was wondering if anyone knows a way that this can be accomplished.

All help you can give is very welcome and will be greatly appreciated.

Thanks,

Wayne.

Thanks you for your fast reply.

The other bits are fine, this will literally be the last touch the code.

Thanks again, very much appreciated.

Wayne.
