Graphics replace the text output below the command field. Graphics and text output may be toggled with the T and G buttons at the top of the screen. Graphics are usually scaled to fill the graphics area. No axis is drawn, because of the constrained screen size. To check the scale, tap anywhere in the graphics area and read the coordinates of the point below the pen.
Most graphical functions support an additional argument to specify the color.
Scripts are simply collections of statements, variable assignments and expressions which are evaluated exactly as if they were written in the command field. They cannot modify the workspace variables you define from the command field or from scripts. Both scripts and functions are entered in an editor window, and are saved in a persistant database. Standard Edit menu commands are available to Cut, Copy and Paste text in LyME or between LyME and other Palm applications such as Memo Pad. Write your statements, typically one per line, below.
