Advantages of Structured Programming Macros

Structured application programs require more discipline at the design and logical structuring stage but they can be coded more quickly. The time required to reach the testing stage is roughly the same, but the benefits of SPMs are significant from this point and onward.

Using the SPMs requires a more disciplined approach to programming and, therefore, provides the following advantages:

• Application programs are easier to read and understand.
• Application programs are less likely to contain logic errors.
• Errors are more easily found.
• Higher productivity during application program development.
• Improved application program design.
• Application programs are more easily maintained.

Using structured programming emphasizes:

• The total logic of an application program.
• What the application program does.
• What the logical flow through the application program should be.

You must consider these aspects before writing detailed instructions. This leads to a clearer application program structure, improved understanding, and a better chance of identifying possible abnormal or error conditions that should be corrected.

Using structured programming techniques also makes it easier for a new application programmer to:

• Read and understand an existing application program.
• Identify modifications for additional functions or correcting errors.
