When you create a compound block, connector tabs are attached to the compound block for each of the following situations:
•All unsatisfied connector tabs on the internal blocks (except global variables)
•All satisfied connector tabs to external blocks
To create a compound block
1. Select the blocks to be encapsulated.
2. Right-click one of the selected blocks and choose Create Compound from the pop-up menu; or choose Edit > Create Compound Block.
3. Under Compound Name, enter a name. Avoid using the dot (.) character in the name; it is used to separate compound block names in the title bar. The default name is Compound.
4. You can apply protection to the compound block, select a picture for the compound block, or hide the block in display mode.
5. Click OK, or press ENTER.
