Error message by VNCRXC06, the ALLOCATE/FREE VNAC host command, after a dynamic allocation or unallocation error has occurred in cmd-name from exec-name.
The value of dyn-DD-name is the name of the file being processed, provided it was specified in the command. Otherwise, it is ?, indicating that the system did not assign a SYS-prefixed name because the command failed.
