Using Structures

A structure is capable of holding dissimilar, but related data as shown in the following example:

The structUutData structure holds strings, dates, and a enum value.

After you create a structure, as explained in Creating Structures, you need to define a variable of that structure type as shown here under Variable sub-nodule:

You can access a structure fields using the member operator (dot). For example, you can access the enStatus field that is a member of the structUutData structure with the following command:

stUutData.enStatus = FAIL

The following example shows how to retrieve a value from the dtStarttime field:

Print stUutData.dtStartTime

Using a Struct to Pass Information

You can pass a structure (and its collection of fields) by using the Structure name as a parameter as in the following example:

DisplayStatus( stUutData )

By using only one parameter, stUutData, the structure name, you can use the DisplayStatus procedure to access the entire collection of fields within that structure.
