IOCA considerations

IOCA resources can be placed in the page segment library and the object container library. On entry to Exit 7, the XTP7RTYP field indicates a page segment resource type if the IOCA object is found in the page segment library; otherwise, it indicates an object container resource type if the IOCA object is found in the object container library. Because IOCA resources reside in libraries with other resource types, IBM® recommends that you establish a naming convention to differentiate these resources. IBM does not enforce a prefix for the eight-character resource name, but you should define a convention that identifies each type of resource. For IOCA resources, IBM recommends a two-character prefix of I1.
