Starts a visual interface for use with MH commands.
vmh [ -prompt String ] [ -vmhproc CommandString | -novmhproc ]
The vmh command starts a visual interface for use with MH commands. The vmh command implements the server side of the MH window management protocol and maintains a split-screen interface to any program that implements the client side of the protocol.
The vmh command prompts for commands and sends them to the client side of the protocol. If the command produces a window with more than one screen of output, the vmh command prompts the user for a subcommand. The vmh subcommands enable you to display specific portions of the command output.
