Enum Kind 

pub enum Kind {
    Stack,
    CommandLine,
    Halted,
    InputForm,
    ChooseBox,
    Message,
    Graphics,
    Input,
    Unknown,
}

What has the keyboard.

Variants

Stack

The stack, no command line open, no program halted.

CommandLine

The stack with a command line open.

Halted

The stack, with one or more programs halted (HALT, PROMPT).

InputForm

An input form (48GX, 49G).

ChooseBox

A choose box.

Message

A message box (MSGBOX, the 49G’s error box).

Graphics

The graphics screen (PICTURE, PVIEW, a plot).

Input

Another loop reads the keys with the command line open: a program waits for input (INPUT), or an editor uses the line (the 49G’s equation writer).

Unknown

Another loop has the keyboard (the interactive stack, the equation or matrix writer, WAIT), or the state could not be read.
