4. A robot language processing apparatus for describing operation details of a teaching-playback robot and teaching the robot, comprising: display means for graphically displaying a picture and capable of designating a position in the displayed picture with pointing means; storage means for storing said robot program as intermediate code; and language processing means for decoding said intermediate codes and connecting orthogonal space positions of a group of motion commands stored in a time-series manner with straight lines or curved lines, converting an obtained group of lines into coordinates in the displayed picture as viewed from an arbitrary viewpoint, graphically displaying the converted group of lines on said display means, and displaying time-series numbers of points in the group of motion commands in superimposed relation to the group of lines on said display means.

The robot language processing apparatus according to claim 4, further comprising a database relative to operations, and wherein said language processing means displays a group of icons indicative of physical operating conditions on said display means, and when one of the icons and an operation interval are selected by said pointing means, said language processing means searches said database based on the selected physical operating condition and the selected operation interval to read operating condition data therefrom, and converts the operating condition data into an operating command.
