Programming Structure Textbook

[CoolBreeze]

I am looking for a good text reference for structuring a complex program. I am using Automation Directs "DirectSOFT32". I am a documentation nut and would like to structure the program in an easy to follow manor if someone goes in behind me to make changes or alterations to the program.

An ISBN# would be great. If sold on Amazon would be better.

Thanks in advance for your time.

I purchased this from Amazon and have found it readable.
Better than the IEC standard.

Robert Lewis's book that was suggested by APB is good.

This one is good too:

With the advantage of not costing you anything.
