Debug Scripts
Table 4.1 Description of the Debugger Buttons
Button Button Name Action
Run
Run without
breakpoints
Break All
Stop
Runs the script in the Debugger until it reaches either a breakpoint or the
end of the script.
Runs the script through the end without stopping and exits the Debugger.
If the script is busy, click Break All to stop all action in the script and return
to the Debugger, for example, if you are in a very long loop.
The debugger may not be able to break execution if the executing script is
waiting on some interactive user action, such as completing a dialog or
interacting with an opened window.
Stops debugging the script and exits the Debugger.
Restart
Disabled. This option might be available in a future release.
Step Into
Step Over
Step Out
Lets you step into a function or an included file. Otherwise, it behaves the
same as Step Over.
Runs all expressions on a single line, or a complex expression that spans
multiple lines, without stepping into a called expression, function, or
Include() file.
Runs the current script or function to a breakpoint or the end and returns to
the calling point. If you are in the main script and the Debugger reaches the
end, the Debugger will close.
Variable Lists
The tabs on the bottom left of the Debugger let you examine global variables, local variables, watch
variables, and variables within namespaces.
Globals The Globals tab lists all global variables and updates their values as you step through the script.
Each variable is added as it is initialized. If there are already global variables defined from running earlier
scripts, they will be listed with their current values when you start the Debugger. See “View Variables”
on page 62.
Locals The Locals tab lists all variables by scope and updates their values as you step through the script.
Select a scope in the menu. See “View Variables” on page 62.
Watch If there is a particular variable or value of an expression whose values you want to watch as you step
through the code, you can add them here. This is particularly useful if your script uses many variables
that might be hard to watch in the Globals or Locals lists. See “Work with Watches” on page 62.
