System
Closes all open files and ends the program
System( [ retval ] )
retval
Closes all open files and returns to the system. An optional return value, an integer, can be specified to return an error code to the system. If no return value is given, a value of 0 is automatically returned. This is the same as End and is here for compatibility between older BASIC dialects. It is recommended to use End instead.
Usage of this statement does not cleanly close scope. Variables and memory are not destroyed automatically and object destructors are not called. Calling the required destructors and other clean-up should be explicitly performed before a System statement.
