Quick question reguarding code in libs

Question

I am currently in the process of just calling an event handler within each of my triggers and having all the code stored in a library, having started this process i released that i cannot refer to :system variables within the lib without causing errors. I.E
IF v_event_name IN ('KEY-DOWN') THEN
IF :SYSTEM.LAST_RECORD = 'TRUE'
THEN     
     MESSAGE('You are at the last record.');
ELSE     
     DOWN;
END IF;
END IF;
this throws an error stating bad bind variable, wheras it would work perfectly in the trigger, am i doing something stupid, or is there anyway round this? If not i suppose this would just have to remain in the trigger?
perhaps im being silly but is there no way to refer to any data block items? such as :cars or whatever.
Thanks in advance.

Hello,
You can refer these variables and forms items by using the NAME_IN built-in..For example..
IF v_event_name IN ('KEY-DOWN') THEN
IF NAME_IN('SYSTEM.LAST_RECORD') = 'TRUE'
THEN     
     MESSAGE('You are at the last record.');
ELSE     
     DOWN;
END IF;
END IF;And same for the form's items. Remember don't use the COLON (:) while referencing the form's item or these variable in NAME_IN built-in.
