This B_CALL puts away the current app, loads the context vectors for a particular builtin app, and calls the appropriate initialization code.
In most cases, this routine will return to the caller after initializing the given app, but for some apps, the page in port 6 will not be restored correctly. Using NewContext instead may be a better choice.
