During compilation, the Editor tool temporarily displays compiler output in the
tab. Once compilation has finished, you can press
to display the current buffer once again.
Additionally, if any conditions were signalled during the compilation, you can view these in the Compilation Conditions Browser by pressing
. You can also locate the source code that generated a message via the context menu, as described in Interactive compilation messages.
You can review the output at any time by clicking the Output tab of the Editor.
