IARVSERV is documented in both the Authorized Assembler pubs and the generic (unauthorized) Assembler pubs. The examples in the Authorized pubs ought to, but do not, show interspace sharing. If I were you, I would submit an RCF. However, the generic/unauthorized Assembler Reference entry for IARVSERV has an example that comes close enough to what you need in Example 6. What Example 6 shows is how to share within an address space... but all you need to add is the source ALET and the target ALET in order to make the jump through the spaces. (The reason the example works within a single space is that the default ALET value (0) in both the source and target specifications; the primary space is just a special case that works well in their example.) -- Tom Schmidt Madison, WI
