Input message pairs are of the form (<name> . <value>). For this block, <name> is ignored. The variable to be set is specified as a block parameter. More information on PMTs in general can be found in PMT Pairs.
Example Flowgraph
In this flowgraph, the input message has the name 'value' and the value of 1 or 0. The Message Pair to Var Block Variable has the value "pressed", so it sets the variable "pressed" to 1. The QT_GUI_Label displays the value of "pressed".
