Symbolic Debugger
Igor´s full-featured symbolic debugger gives you a powerful tool to get your code working properly by observing it execute one step at a time.
The debugger window will automatically appear when one of the following events occurs:
- An error occurs, and you have enabled Debug on Error.
- An error dialog is presented, and you click the Debug button.
- A breakpoint that you previously set is encountered.
You can set breakpoints simply by clicking in the procedure window´s left margin:
Once in the debugger, you can execute a single line of code by pressing the yellow arrow button, step into or out of a routine with the blue arrows, resume execution by pressing the green arrow button, or stop executing with the stop-sign button.
You can view the routine that is currently executing and the chain of routines that called it in the Stack list. The top list item is the routine that began execution and the bottom item is the routine currently executing. You can examine the variables associated with any routine in the Stack list by simply selecting the routine:
You can view the values of all user-defined and built-in variables along with the variable type. And you can edit variable values by double-clicking their current value.
IGOR 5´s structures and wave contents can be examined and edited, too:
You can enter expressions that use local or global variables. The expression´s value is evaluated at every step of the program.
