6.1.4. Block FoldingΒΆ

To facilitate comprehension of the program, blocks of text can be elided so that they do not appear. Each construct that spans more than one line has a control on the left of the screen that allows the user to expand or collapse the corresponding text.

The following illustration shows the folding control (the blue “lozenge” with a dash inside) to the left of procedure Process, prior to the user invoking the elision.

Block Folding Before

By clicking on the dash, the user elides the procedure Process, as the following illustration shows. Note the dash becomes a plus sign, indicating that the control will now expand the unit if invoked. Note also the elision marker at the end of the elided declaration of Process.
