I used it once, when developing the first versions of REXXHTTP. It's extremely annoying to have to add a handler which simply propagates the condition upwards to every routine. Annoying, and error-prone, as it gets too easy to forget one handler, in a particular routine. And it's aesthetically unpleasant too. >From then on, I resorted to use SYNTAX. For example, my new parser uses a 98.900 and stores all relevant stuff in the ADDITIONAL array. If USER conditions are to be usable, their design needs to be improved. I think that your suggestion is a good step in the right direction. Josep Maria
