I'm lost here. Yes I'm talking about Surfer Grid Formats, and there 3 of 
them (I'm pretty sure on this)

'DSBB' for what the now call GS Binary (*.grd) format <../topics/surfer_6_grid_file_format.htm> and used to be the grid format up to version 6
'DSRB' for the default (complicated and un-necessary large) Surfer 7 (*.grd) format <../topics/surfer_7_grid_file_format.htm>
