About Structures

Structures are one kind of ATEasy user-defined data type. Structures are used:

To group variables of different types under one variable. This provides a convenient way of passing many parameters from one procedure to another using a variable of type Structure.
To pass one combined argument rather than many arguments by DLL's procedure or by ATEasy.

This chapter includes the following topics:

Topic	Description
Creating Structures	Explains how to create new structures, add fields, and change field properties.
Nesting Structures	Describes how you can nest structures within structures.
Using Structures	Explains how a structure holds dissimilar, but related data, how to access a field using dot notation, and how to use a structure to pass data.
Matching Requirements of External Programs	Describes how ATEasy communicates with external programs using structures as arguments. An example shows how to match a C-Style structure to an ATEasy structure.
Assigning Structs to Structs /Variants	Describes special assignment operations with structures, namely Assigning Structures to Variants and vice versa, and between same type of structures.
