PICbasic and 40X4 lines LCD

Good day ,
I have to interface a 40 chars by 4 lines LCD to my PIC micro . There are two enable lines ( E1 and E2 ).
E1 is for the first HD4470 which controls the first and second line,
E2 is for the second HD4470 which controls the 3rd and 4th line.

Any help in using PICbasic Pro for this application ?

Thanks
