   Figure 3. Action list

2. Use <Up/Down Arrows> to choose the action.
3. Press <Enter>.

Run - executes a part of the program (or the whole program) from the first unexecuted operator to the end.

Note: The first unexecuted operator is marked as inverted in colors. If there are no marked operators or the first one is marked then it means that no operators have been executed.

Go to - executes a part of the program from the first unexecuted operator up to the one where the pointer is not including it. If the operator where a pointer is located precedes the unexecuted one then it will be executed as part of the program from the first unexecuted operator to the end.

Step - executes the first unexecuted operator.

At the very beginning when no operators have been executed no operator is marked. The first pressed Step marks the first operator. Any next chosen Step executes the following operator.

The first press of <Esc> removes impression from the operator that is currently marked.

If upon executing the program, the wrong operator is met then you will see a message about what error occurred. On that instance, the pointer will move to the wrong operator and the impression will be removed from the currently marked one. The program will then be executed from the very beginning.

Show - shows result of all executed operators (see Fig.4):
