Contour Plots   (details) Prime   EN   3KB/1KB
Creates 2D contours using the Advanced Graphing app. The user's current formulas are kept safe, and are restored after the contours are drawn. I had hoped to incorporate this into the Graph3D app, but the current implementation of startview() and how apps handle built-in applications are currently preventing this from happening.

DOROMP2 1.0   (details) 49/50   EN   69KB/1KB
This is an example of how to implement one's own prologue. This specific example shows how to implement a prologue that behaves like a ROMPTR. It requires that the matching ROMPTR contains a BZ-compressed string object, and will automatically decompress and execute the object, even from covered memory banks. Make sure to store the library in Port 0!
