Programming Microsoft Dynamics NAV - Fifth Edition

By: Marije Brummel, David Studebaker, Christopher D. Studebaker

Overview of this book

Microsoft Dynamics NAV is a full business solution suite, and a complete ERP solution that contains a robust set of development tools to support customization and enhancement. These tools provide greater control over financials and can simplify supply chain, manufacturing, and operations. This book will take you from an introduction to Dynamics NAV and its integrated development tools to being a productive developer in the Dynamics NAV Development Environment. You will find this book very useful if you want to evaluate the product's development capabilities or need to manage Dynamics NAV based projects. It will teach you about the NAV application structure, the C/SIDE development environment, the C/AL language paired with the improved editor, the construction and uses of each object type, and how it all fits together to build universal applications. With this new edition, you will be able to understand how to design and develop using Patterns and new features such as Extensions and Events.

Flow control

Process flow control functions are the functions that execute the decision making and resultant logic branches in executable code. IF-THEN-ELSE, discussed in Chapter 6, Introduction to C/SIDE and C/AL, is also a member of this class of functions. Here, we will discuss the following:

  • REPEAT - UNTIL
  • WHILE - DO
  • FOR-TO and FOR-DOWNTO
  • CASE - ELSE
  • WITH - DO
  • QUIT, BREAK, EXIT, and SKIP

In that sense, REPEAT-UNTIL defines a block of code, operating somewhat like the BEGIN-END compound statement structure that we covered in Chapter 6, Introduction to C/SIDE and C/AL. REPEAT tells the system to keep reprocessing...
