Workflow Entry: Workflow Pattern - Structured Loop (B)

This workflow is an alternative GWorkflowDL representation of a structured loop that updates the variable "x" in each iteration and which models the control flow separately from the index "i".

Here a version of the graph with manual graph layout:

This workflow is equivalent to the following pseudo code:

x:=0;
for ( i:=0; i<=99; i++) {
  x:=x+i;
}
x_result:=x;

Please remark that this demonstration workflow does not invoke any external services at all. The calculation is done only by using the GWorkflowDL's syntax and semantics.
