2 – Description
The BACK Analyzer command is one of a series of directional commands that allows you to traverse a program's structure. The BACK command displays the current plot, and positions an arrow to point to the bucket with the next highest number of data points (the previous leaf). The corresponding source lines for that portion of the program are displayed alongside the plot. Other traverse commands are FIRST, NEXT and CURRENT.
