Modular programming with Pascal
Jørgen Steensgaard‐Madsen · Software Practice and Experience · 1981
Abstract A technique is presented by which the programming language Pascal as defined by the expected standard, can be used to write programs divided into modules containing mutually hidden information. The technique fits nicely with the programming by stepwise refinement methodology, combines top‐down and bottom‐up methods, and illustrates that stepwise refinement does not necessarily lead to simple tree‐like programs. Limitations for the application of the technique with Pascal are pointed out.
