The Debug view shows one or more session trees for each active Debugger session. It also displays all the running agents on the broker which is attached to the Progress Developer Studio for OpenEdge Debugger during remote debugging. It changes dynamically as agents are added or removed from the attached broker.
The Debug view also provides the program execution commands that you use to step through the code.
The Debug perspective includes the Debug view by default. If the view is not open, select from the Debugger perspective to display it.
Session tree Debug view
The session shows the contents of the ABL stack trace (lines marked
with ) for the currently executing procedure in each active
debugging session. In its initial state, the session tree shows the following
entries:
The stack trace changes dynamically as you step through the code, adding and removing entries that indicate the execution sequence of the current procedure. The current line appears at the top of the stack.
You can investigate the code associated with a line of the stack trace by clicking on the stack trace line. The ABL Editor window containing that code becomes active, and the Variables view, the Expressions view, and the Dynamic Objects view show data values as they are immediately preceding execution of the selected line.
See Using the Debug view and stack trace for more information.
Program execution commands
The following commands are available on the Debug view toolbar and context (right-click) menu:
| Command | Action |
|---|---|
| Step Into |
Execute the current
line and continue until reaching the next executable statement,
which may be in the current procedure, a subprocedure, or a trigger.
That statement becomes the current line, and it is not executed
until you continue. See also the information about garbage collection in Code stepping. |
| Step Over |
Execute the current line and continue until reaching either a breakpoint, or the next executable statement in the same procedure. Thus, if the current line calls a subprocedure or causes a trigger to execute, the subprocedure or trigger is executed without interruption unless there is a breakpoint. In other words, step "over," not "into," the subprocedure or trigger. |
| Step Return |
Execute the current line and continue either until reaching either a breakpoint, or until the current procedure ends and returns control to the calling procedure. |
| Resume |
Execute the current line and continue without interruption until reaching either a breakpoint or the end of the program. |
| Suspend |
Interrupt execution
following completion of the current instruction and give control to
the Debugger at the next executable statement. Also, suspend the attached AVM. |
| Terminate |
Interrupt execution and end the Debugger session. |
| Remove All Terminated
Launches |
Clear the Debug view of session trees that are no longer active. |
| Disconnect |
Disconnect from the attached AVM and stop receiving notifications from the running external AVM. |
