Question
What function the Solidworks parallel constraint symbol mean in MathCAD?
In investigating an unrelated problem, I found a very useful xmcd file on this discussion board. But there is a symbol I don't recognize. Can someone tell me what the circled operators in the image below do?

Also a nice feature would be to hover over an operator and for a popup to appear saying what the operator is and link to the help file for that operator.
