Unfortunately it was not. According to a post by Richard Nelson in the old forum, Bill Wickes was actually working on it, but in the end didn't have enough free time to finish it. Here was his dilemma: "If his son went away to college he would finish the manuscript, if he stayed home, he would not. His son stayed home."

This is very unfortunate, because the biggest changes in the GX precisely pertain to the subject matter of the second volume, namely to what Bill Wickes refers to as "Problem Solving Resources", in other words the SOLVE, PLOT, ALGEBRA/SYMBOLIC, TIME, STAT, and UNITS environments.
