MCI

Syntax

MCI command

MCI command command ...)

Explanation

MCI provides an interface to the Windows 3.1 multimedia extensions. MCI works much like the TYPE command. Instead of printing its inputs, however, the resulting text is sent to the MCI command line interface and executed by Windows.

Some of the MCI commands return values. Logo collects these values into a list which is the output of this command. The default output value is the empty list [].

The Multimedia Command Interface help can be invoked with the Help/MCI commands... menu command.
