Use of CALL command

[wombat953]

Can someone pls. tell me how to use the call( EFSName, args ) command? Specifically, I am looking to invoke the CCI function, for the current value, and the one immediately prior to that.
Thank You

You can find a very basic (and still incomplete) write up on call() and callFunction() by clicking here
