Searches across all CRPLCore units looking for any that have a script that contains the specified variable with the specified value. Useful for finding units by name, or other value. The function pushes the n UID's onto the stack followed by the integer n, where n is the number of units.

Note that a single core can have multiple scripts assigning VariableName to different values, any of which can be used to find the core.
