The following toolkit allows the programmer to perform on-screen scrolls in all directions, as many times as desired, directly from BASIC, i.e., without the use of POKEs. The routine is relocatable, meaning it can be loaded at any memory address and executed. In BASIC, we use the form: INPUT USR adr,dir,fois. Where adr is the address of the routine, dir is the direction of the scroll, and fois is the number of times the scroll is executed.
