More About Variables and Fields

A variable is a list of fields. Each function has its own set of variables that are used to:

• Pass values between the function and panels, reports, views and other functions
• Temporarily store interim values during processing

When you perform operations on fields in an action diagram you always specify the variable to which the field belongs. The same field can (and typically does) appear in more than one variable. Consider the statement you just entered. The Project ID field appears in both the InsertP and SharedData variables. Each instance of the field can store a different value.

To specify the variable to which a field belongs you use the syntax:

variable <field>

For example, this refers to the instance of Project ID in the InsertP variable:

InsertP<Project ID>
