Collapsing and Expanding Paragraphs or Subprograms

In very long programs, it may be helpful to display the names of paragraphs or subprograms only and hide their source code. To collapse paragraphs or subprograms, choose Edit > Collapse All. Click the plus sign (+) next to a collapsed paragraph or subprogram to show its source code again. To show the source code for all collapsed paragraphs or subprograms, choose Edit > Expand All.
