Viewing a List of Variables Figure 198: The Tools > Expression List Window Showing Column Selector You can use the Window > Update All command to update values in all other Tools > Expression List Windows. Reopening Windows: If you close all open Tools > Expression List Windows and then reopen one, TotalView remembers the expressions you add. That is, if the window contains five variables when you close it, it has the same five variables when you open it. The thread TotalView uses to evaluate the window’s contents is the Process Window from which you invoked the Tools > Expressions List command. Rebinding Windows: The values displayed in an Expression List Window are the result of evaluating the expression in the thread indicated in the Threads box at the top of the window. To change the thread in which TotalView evaluates these expressions, you can either type a new thread value in the Threads box or select a thread from the pulldown list in the Threads box. (Changing the thread to evaluate expressions in that thread’s context is called rebinding.) Restarting a Program: When you restart your program, TotalView attempts to rebind the expressions in an Tools > Expression List Window to the correct thread. Unfortunately, it is not possible to select the right thread with 100% accuracy. For example, the order in which your operating system creates threads can differ each time you run your program. Or, program logic can cause threads to be opened in a different order. You may need to manually change the thread by using the Threads box at the top of the window. Seeing More Information When you first open the Tools > Expression List Window, it contains two columns, but TotalView can display other columns. If you right-click on a column heading line, TotalView displays a context menu that indicates all possible columns. Clicking on a heading name listed in the context menu changes if from displayed to hidden or vice versa. Even when you add additional columns, the Expression List Window might not show you what you need to know about a variable. If you dive on a row 308 Chapter 14: Examining and Changing Data
Viewing a List of Variables (or select Dive from a context menu), TotalView opens a Variable Window for what you just dove on. You can combine the Expression List Window and diving to bookmark your data. For example, you can enter the names of structures and arrays. When you want to see information about them, dive on the name. In this way, you don’t have to clutter up your screen with the Variable Windows that you don’t need to refer to often. Sorting, Reordering, and Editing This section describes operations you can perform on Tools > Expression List Window data. Sorting Contents: You can sort the contents of the Tools > Expression List Window by clicking on the column header. After you click on the heading, TotalView adds an indicator that shows that the column was sorted and the way in which it was sorted. In the figure in the previous topic, the Value column is sorted in ascending order. Reordering Row Display: The up and down arrows ( ) on the right side of the Tools > Expression List Window toolbar let you change the order in which TotalView displays rows. For example, clicking the down arrow moves the currently selected row (indicated by the highlight) one row lower in the display. Editing Expressions: You can change an expression by clicking in it, and then typing new characters and deleting others. Select Edit > Reset Defaults to remove all edits you make. When you edit an expression, TotalView uses the scope that existed when you created the variable. Changing Data Type: You can edit an expression’s data type by displaying the Type column and making your changes. Select Edit > Reset Defaults to remove all edits you make. Changing an Expression’s Value: You can change an expression’s value if that value is stored in memory by editing the contents of the Value column. About Other Commands: You can also use the following commands when working with expressions: Edit > Delete Expression Deletes the selected row. This command is also on a context (right-click) menu. If you have more than one Expression List Window open, deleting a row from one window deletes the row from all open windows. Edit > Delete All Expressions Deletes all of the Expression List Window rows. If you have more than one Expression List Window open, deleting all expressions from one window deletes all expressions in all windows. TotalView Users Guide: version 8.7 309
