source: trunk/FACT++/src/InterpreterV8.h@ 16862

Last change on this file since 16862 was 16802, checked in by tbretz, 11 years ago
Allow arguments to be given to the interrupt handler and added a possibility to trigger an interrupt also from within the script; some modification to the way code is executed so that return values are only printed really when some code is finished from the command line, but not for include or when the main program is run.
