Displaying the Call Stack

• From the menu bar - Choose the Where selection from the Debug menu. The Where window is displayed; see Figure 4-4. The window contains the call stack; it is updated automatically when execution stops or when you issue commands that change the stack.

Figure 4-4 Where Window

• From the command window - Issue the where command on the command line. If you include a number, it specifies how many active procedures are to be displayed; otherwise, all active procedures are displayed in the history region.

Values of arguments in displayed procedures are shown in the default radix, which is decimal unless you change it via the set $radix command; see " Changing the Default Radix".
