An attempt to vary a loadlib offline results in the message DC277907 V1 LOADLIB V0002 NEVER ACCESSED -- NO ACTION
This DC277907 message is issued when a loadlib is in a CLOSED status. A loadlib is only ever in a CLOSED status at startup and before anything has been loaded from it. If an attempt is made to vary it ONLINE or OFFLINE while CLOSED, message DC277907 is issued.
This makes it problematic to vary a loadlib OFFLINE if it is CLOSED. Since it can't be varied ONLINE or OFFLINE, the only way to get it to go OFFLINE is to force a dummy load of any program so that the CV will automatically vary it ONLINE, and then the user can vary it OFFLINE manually.
This, along with the fact that message DC277907 includes the following text:- "An attempt has been made to vary online a load library that was never varied offline ..." means that is possible that the original intention is that DC277907 should only be issued on an attempt to vary a CLOSED loadlib ONLINE, not OFFLINE.
