# Screen Scrolling

This article shows how a routine can he written and entered into a ZX80 that enables the user to SCROLL the display. In the 4K monitor there is no facility at all for doing other than printing to the last line of the display, and then, when the display is full, the program will stop unless a CLS (clear screen) command is used.
