    You can use the Tools/Insert variable menu option or the button on the main toolbar to do this - see the figure below.


    The little red square represents variables

    The Turing programs and Visual Turing use Greek symbols for the variables. For a easier use of them, in Visual Turing the names of the Greek symbols are written with the symbol. The variables are used to retain symbols. The loading of a variable is made by placing it as the left operand in a condition on an arrow- see Modifying the condition of the arrow
