User interface > Debugging and executing > Execution at a stretch
If you execute a program at a stretch, the input will be parsed till its end or up to an error. This can be done in two modes
Start (F9)
In this mode the execution will be stopped at break points and then can be continued step by step. If an error occurs, there will be detailed information about the circumstances.
Execute (F10)
This mode is for the fast execution of ready programs. Some steps, which are made in the other mode, here are left out. But there will be given only general information, if an error occurs.
