External Variables

If from a Process (Process A) you run a different Process (Process B) by using the "Start Process" action, all variables of Process A are available to Process B. These variables in Process B are considered "External Variables" and can be used for passing data from one Process to another.

For Process B to access any of the external variables, the "ext:" prefix must be included before the variable name. For example, if Process A defines a variable %MyData%, Process B can access the value of that variable using the notation: %ext:MyData%
