Name
Run -- asynchronously execute a program
Synopsis
Run(file$[, resetkeys, userdata])
Function
This function executes the program specified by file$ asynchronously. The string file$ can also contain arguments that shall be passed to the program. If you need to execute a program synchronously, you have to use the Execute() function.

If supported by the operating system, this command can also be used to view data files like documents or images using their default viewer.

On Android file$ has to be either a data file like a JPEG image or a package name like com.airsoftsoftwair.hollywood if you want this function to start another app.

If you want to be informed when the program started using Run() is terminated, you can install a listener for the RunFinished event handler using InstallEventHandler(). See InstallEventHandler for details.

Due to historical reasons this command expects program and arguments in just a single string. This means that you need to be very careful when passing program paths that contain spaces since the very first space in file$ is interpreted as the separator of program and arguments. If you want to start a program whose path specification uses spaces, you need to use double quotes around this path specification or it won't work. See below for an example.

The optional argument resetkeys is only interesting for advanced users. If this is set to False, Run() won't reset all internal key states after executing the program. By default, all key states will be reset when Run() returns because programs started using Run() often assume the keyboard focus and Hollywood might be unable to reset its internal state flags because the new program started via Run() takes over keyboard focus. That's why by default Run() will reset all internal key state flags when it returns. Disabling this behaviour can make sense if you use Run() to start programs that don't have a GUI and don't take away the keyboard focus.

Starting with Hollywood 6.1 there is a new optional userdata argument. This argument can be used to specify user data that should be passed to the RunFinished event handler that can be installed via InstallEventHandler(). See InstallEventHandler for details. The user data can be of any type.

Inputs
file$
command-line-like string that specifies program and arguments
resetkeys
optional: whether or not internal key states should be reset when this call exits (defaults to True) (V5.1)
userdata
optional: user data to pass to RunFinished event handler; this can be of any type (V6.1)
Example
Run("Sys:Prefs/Locale")
The above code executes the locale preferences on AmigaOS based systems. Your script's execution will go on immediately after executing the locale program (asynchronous execution).


Run("\"C:\\Program Files (x86)\\Hollywood\\ide.exe\"")
The code above runs the Hollywood IDE on Windows systems. Note that we've embedded the program specification inside double quotes. This is absolutely necessary because the first space in the string passed to Run() is normally interpreted as the separator between program and arguments. If we didn't use double quotes in the code above, Run() would try to start the program "C:\Program" and pass the arguments "Files (x86)\Hollywood\ide.exe" to it which we obviously don't want.
