Hi Sreenivas
What problem are you seeing when you run the file?.
Your text style setup at the start appears to be in the correct format with Option 808 followed by Option 001.
I notice that there is another 808 option at the end of the file, this is blank in relation to font so it will reset to the installation defaults. If you delete that line it will stay with the original Option 808 setup.
