But I'm given to understand that none of that information is helpful when a called program receives control from a 2nd- or 3rd-party caller (i.e., any caller not written on-site) in terms of being able to tell how much storage the caller allocated for the savearea whose address is passed to the called program. Now, if I've got that wrong, then please enlighten me. Thanks.
