radio button missery

Im just giving a name to one of the items of my radio button. one of the item was named STRAWBERRY. I compiled the program and got this error:

The parameter name ("STRAWBERRY" here) can be up to 8 characters long.

Does this mean ABAP cant allow more than 8 character on an item name of a radio button? Doesnt sound good and logical for me. im just a newbie. how to solution this? What if i need a name longer than 8 characters or what if I need 3 words on that name?

thanks for the help.
