I had a look at the idea back in 2007 - in UniBasic and SB+. http://mvdbs.com/2007/08/01/try-and-catch/ and http://mvdbs.com/2007/08/16/try-and-catch-part-2/ .
SB+ was easier as RTN.FLAG is used throughout the system and can quite easily be used as the exception catch. Within UniBasic, there is already @SYSTEM.RETURN.CODE and @USER.RETURN.CODE. @SYSTEM.RETURN.CODE is currently used by a number of statements e.g. PERFORM; so it should be possible to just extend upon that. It really would be a nice feature to be added. Anyone here a paid-up member to the Rocket U2 club and can put a word in?
