5.1 Editing the Block Properties

The block properties contain additional information about the block.

Optional data such as name, family, version and author of the block can be

entered here. The properties also include other statistical data and further

information, automatically entered by the system, which cannot be edited by

the user (see Figure 5-1). You can also assign system attributes to the block.

The block properties provide you with important information about the block

type, memory requirements and time of the last modification. This can be

useful when trying to track down errors, such as insufficient memory and

time stamp conflicts.

The block properties can be edited using a dialog box.
