State machines maybe?

"while in state A if event 1 occures goto state B, otherwise if event 2 
occures goto state C"

There are tools that let you design state machines using simple charts. 
Some of them (like ZMech at http://www.xcprod.com) will even generate the 
code for you and allow you to interactively trace and debug it.
