Work with Classes window
The
Work with Classes window appears after clicking
(Work with Classes) from the main window.
The upper part of the window contains a list of classes, which is continuously updated according to the functions performed. Below the list is a group of objects that map to all the data elements of the selected class.
The following table describes the columns and fields listed in the Work with Classes area.
Note: If the corresponding
Min and
Max fields maintain their default values, the data range is ignored and only the
Data type value is considered.
