TI-Basic Z80 Programming/List of Commands/Pt-On

Pt-On(X,Y TI Basic programming instruction, accessed from within the program editor by pressing 2nd+PRGM+Right+Enter. Plots a single point at the X and Y coordinates, using the default (user-set) or program specified Window and Zoom settings. Unofficial usage of function (not specified in TI manual): Pt-On(X,Y,Z Plots a point at the location specified by X and Y. Meaning of Z: If Z is 1, a normal point is plotted If Z is 2, a 'square' point is plotted If Z is 3, a 'cross' point is plotted This function is particularly useful for games, where you may need bigger points and do not want to use multiple Pt-On instructions. If you have ever changed Stat options, the points that are plotted by this function are the three types that can be used for scatter plots.
