Setting 'it' in caller

[Dar Scott]

How do I put a value into the instance of 'it' in the calling function?

For example, suppose I want to create a custom command 
'getCurrentRobotName' that returns an error in the result and the 
current name in 'it'.  This is 'it' in the handler that invokes 
'getCurrentRobotName'.
