No. Now that you have a binary data file, the contents of what you  
call 'control.gs' is a data descriptor file that describes what's in  
your binary file. Descriptor files usually have a ".ctl" extension. To  
read this data with GrADS, you use the open command:

ga-> open 7hA01.ctl

where 7hA01.ctl contains this:

I STRONGLY suggest you take some time to read the User's guide, and  
then run through the tutorial before continuing.
