Data Flow Icons

Two types of flow lines are allowed in activity charts: data flow lines, drawn as solid arrows, and control flow lines, drawn as dashed arrows.

 
Create Flow Line - establishes a data flow between two activities. Typically, data flow lines carry information that is used in computations and data-processing operations
Label Existing Flow Line - enables you to name a flow line that denotes either a single information element that flows along the line or a group of such elements.
Flow labels in activity charts, module charts, and information-flow elements can be any primitive (variable) data element (event, condition, data-item) or information flow. In addition they can be elements on any level of a primitive data element (array element, array slice, and record/union field). Array elements can use only literal constants.
