I never heard of such a thing, so I looked it up. It is a rather bizarre requirement that seems to me to contradict the standard linkage conventions that it claims to follow. It means that a program must know not only its own storage requirements, but the storage requirements of every program that it calls, and every program that they call, etc. There is no mechanism to verify that the allocated storage hasn't been exceeded, or to ensure that the storage that is obtained is adequate. https://www.ibm.com/support/knowledgecenter/SSLTBW_2.2.0/com.ibm.zos.v2r2.ccrug00/mvslnkcnv.htm -- Tom Marchant ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
