libraries defined for that resource type (for example, PDEFLIB for page
definitions). The libraries you specify can contain any AFP resources (fonts,
page segments, overlays, page definitions, or form definitions). If Resource
Access Control Facility (RACF) is installed on your system, RACF checks the
authority of the USER ID requesting access to a user library (data set). If ACIF
is not authorized to allocate the data set, it reports an error condition and
terminates processing.
EXAMPLE
USERLIB=USER.IMAGES,USER.AFP.RESOURCES
Notes:
1. Because AFP resources (except page segments) have reserved prefixes,
naming conflicts should not occur.
2. An inline resource overrides a resource of the same name contained in a
USERLIB parameter.
3. The files must be specified as fully-qualified names without quotation marks.
4. For systems before MVS/DFP Version 2.3, data sets must be concatenated
with the largest block size first.
