Miscellaneous restrictions for using data-in-virtual

When you attach a new task, you cannot pass ownership of a mapped virtual storage window to the new task. That is, you cannot use the GSPV and GSPL parameters on ATTACH and ATTACHX to pass the mapped virtual storage.
You cannot invoke data-in-virtual services in cross memory mode. There are no restrictions, however, against referencing and updating a mapped virtual storage window in cross memory mode.
You cannot specify a non-shared standard hiperspace as a DIV object (DIV ACCESS) if you have issued ALESERV ADD for that hiperspace. You cannot issue ALESERV ADD for a non-shared standard hiperspace while it is a DIV object.
