Connecting/Disconnecting Flags
To connect a flag symbol to two module symbols you must first have created a “call” between the modules. To create a call, use a call command from the Draw Menu or from the Toolbox, and place the call line using the instructions for placing line symbols.
To connect the flag symbol to the call symbol
1 Select both symbols using one of these methods:
Use the Multiple Select command or the Boundary Select command in the Edit menu.
Hold down the right mouse button while clicking with the left button.
2 Use the Connect Flags command in the Draw Menu.
To disconnect a flag from a call, select only the flag symbol and use the Connect Flags command again. This command works as a toggle, and the arrowhead will return to white.
