text to binary file

[Aditsuda Jamroensan]

Dear GrADS user

    I'm a new user. I want to convert text file to binary file. I went
through the section 'Creating a station file' but I didn't understand some
codes.

My question: What does FORM='UNFORMATTED', RECORDTYPE='STREAM' mean?
and Could any one give me Fortran90 example codes to change text file to
binary file?

Thanks
