Figure 7: A snapsnot of the Pascal Genie running a program. The source code window (left) shows the currently executing line highlighted with several procedure bodies elided (indicated by elipses, expanded by clicking on them). The large window in the background is the call stack showing all of the data on the stack. Some variables are elided completely, some are shown by their name only, and the charTree is shown fully expanded with an automatically generated binary tree showing the data. The programıs Input and Output appear in the window near the bottom right and the execution control panel appears at the bottom.
