To set breakpoints at positions which are currently not visible (e.g. because the source-
window of that module is not open), you can also enter a symbolic label directly in the
“Breakpoint” menu. Example: Enter “main” in the address-field and confirm. The new
breakpoint will automatically be assigned to the address of the “main()”-function.
