Rory,
The Cancel and Exit flags are set after every return from an IBM

First I executed STRSEU unprompted (via QCMDEXC and a wrapper) and called QUSRJOBI after. 'Cancel' en 'exit' were both '0', whether I changed the member or not.
Then I executed STRSEU prompted: - When I canceled the prompt with F12 'cancel' was '1', 'exit' was '0' - When I canceled the prompt with F3 both 'cancel' and 'exit' were '0' - When I entered SEU both 'cancel' and 'exit' were '0'.The second case seems strange: I would have expected 'exit' to be '1'. Don't know why that is; documentation says no more then 'Whether the user pressed the cancel/exit key ' and 'The application or command that was called before this API determines how the key is set'.
(BTW: SEU issues a message EDT0229 when it actually changes a member. In a similar case like yours I check for this message to determine whether the user changed the member.)
