These routines apparently >need to receive and send arrays and he wants to know how to handle that. You cannot pass arrays between functions in I4GL. Period. You cannot pass arrays into C functions called from I4GL. You cannot pass arrays from C functions to the calling I4GL code. You cannot define arrays in C code which are referenced in I4GL. (Actually, if you're really nifty with your understanding of globals files, you can, but it isn't recommended if you have to ask questions about it). You can define global arrays in I4GL which can be referenced from C -- you just have to be very careful to get the C definitions correct.
