What you want to do is leave the call stack entry at '*' (current call stack entry) and change the call stack count to 1 (previous x entries). This will send the message to the caller of die.

Hey all, I'm trying to figure out the correct way to throw an exception from an RPGLE program. I'm working on a program where I need to use the profile handle api's to become another user for a short time. Should any of the api calls fail, I want to signal an exception, and if the new user is active, be sure that it's priviliges get dropped. (See test code below). I'm calling QMHSNDPM to signal the exception, and I've wrapped it into a procedure to make it easier to call, as in die('Uh-oh something bad happened'). In the call to the send program message api, if I set the call stack entry to '*', and the call stack count to 0, then the message is: Message ID: RNQ0202 Type: Inquiry Sev: 99 The call to 'DIE' ended in error. RPG procedure ZZZ_PH in program LIB/ZZZ_PH at statement 9700 call program or procedure DIE which ended in error. This is not terrible, as the program and statement number are listed in the second level text, BUT, I really need the message to be: The call to ZZZ_PH ended in error. Mainly because I might have a hundred programs using the die procedure, and It would be much easier to debug if the _caller_ of die is listed in the first level text. So, I started playing around with the call stack entry and the call stack count. In the case where the call stack entry is the name of the program ('ZZZ_PH') and the call stack count is set to zero, I get the same results as above, namely an RNQ0202 inquiry, sev 99, and the same text. In the case where the call stack entry is the name of the program, and the call stack count is set to one, I then receive a much different result. In this case, I receive no inquiry message, and the program returns to the command line with the following error listed at the bottom of the screen: Message CEE9901 Type INFO Application error. CPF9898 unmonitored by ZZZ_PH at statement *N, instruction x'0000'. Then application ended abnormally because an exception occurred and was not handled. So, what is the proper way to die, such that the _caller_ of the die procedure is listed in the first level text? Can it be done?
