Structured Programming
STEP 5 allows the creation of structured or unstructured programming, from simple AND/OR operations up to complex subroutines. A STEP 5 program may, therefore, contain thousands of statements.
To maintain maximum transparency, STEP 5 offers a number of structuring facilities:
- Block technique - A linear operation sequence is divided into sections and packed into individual blocks.
- Segments - Within blocks, fine structuring is possible by programming subtasks in individual segments.
- Comments - Both a complete program as well as individual blocks or segments and individual statements can be directly provided with comments.

Famous quotes containing the words structured and/or programming:
“Just as the constant increase of entropy is the basic law of the universe, so it is the basic law of life to be ever more highly structured and to struggle against entropy.”
—Václav Havel (b. 1936)
“If there is a price to pay for the privilege of spending the early years of child rearing in the driver’s seat, it is our reluctance, our inability, to tolerate being demoted to the backseat. Spurred by our success in programming our children during the preschool years, we may find it difficult to forgo in later states the level of control that once afforded us so much satisfaction.”
—Melinda M. Marshall (20th century)
