converting RSI from meta4 to meta5?

 
Deal all,
Hi. How can I convert these two lines from meta4 to meta 5? The Capitals are just for example. I just need to convert the definition because when I use iRSI, I receive errors as undefined. Thank you for your help in advance.
   Rsi1 = iRSI(A,B,C,D,F);
   Rsi2 = iRSI(G,H,I,J,K);
