CPL/ATPL (A) / (H) / (G) / etc. is the reference to the type of aircraft, (F) doesn't exist to my knowledge. I don't know if there is any convention for frozen ATPL, I always spell it out in full to avoid ambiguity.
This was the most involved application form I have ever filled out, felt like being at the interview already. I hope they like my ramblings tomorrow...
