To Create a Script that Changes Settings in a Drawing

This script turns on the grid, sets the global linetype scale factor to 3.0, and sets layer 0 as the current layer with red as the layer's color.

1. Launch a text editor that saves in ASCII format (for example, Notepad on Windows or TextEdit on Mac OS).
2. In the text editor, enter grid on.
3. On the next line, enter ltscale 3.0.
4. On the next line, enter layer set 0 color red 0.
5. Add a blank line.
6. Save the file in the ASCII text format (TXT file), with a file extension of .scr.

   The script file may contain comments, as follows:

; Turn grid on

; Blank line above to end the LAYER command
