Compressing Unused Space in the Data Structure Diagram

[,COMPRESS= < ON  > ]
            \ OFF /

specifies whether or not you want CA IDMS Schema Mapper to remove unused space (created by LOCATE statements) between record blocks in the diagram.

This parameter is valuable when you are using LOCATE statements and executing CA IDMS Schema Mapper iteratively to modify the layout of a diagram. See LOCATE Statement for a complete discussion. With this parameter, you can wait until a diagram nears completion to compress it.

When COMPRESS=ON, CA IDMS Schema Mapper compresses the diagram, eliminating unused space, after all record blocks have been positioned in the diagram.

Default: The default value is ON.
