MOSES vessel modelling

Hi all.. I a trying to learn MOSES the hard way, from the reference manuals, online tutorials and looking at the files from vessel library. I am creating the model of a semisubmersible of arbitrary dimensions, for hydrodynamic analysis. I have reached this stage after few trial and error. I have been writing commands in the command line. I have also given those steps below. I have tried a lot but, still not been able to figure out how to create DAT file and CIF file. Is there any command to save the current status of the model to a DAT file? Also, I have used the &SURFACE command till now. Should I define panels separately from here or create a mesh? I know these are lot of questions but, I am really stuck here. Any help or hint would be appreciated. Thanks.
