Introduction to Procedural Programming. Procedural Programming Tutorials. Procedural programming. Procedures and modularity[edit] Scoping is another technique that helps keep procedures strongly modular.
It prevents the procedure from accessing the variables of other procedures (and vice-versa), including previous instances of itself, without explicit authorization. Because of the ability to specify a simple interface, to be self-contained, and to be reused, procedures are a convenient vehicle for making pieces of code written by different people or different groups, including through programming libraries.
