744.0. "OA$FBT_LIST_LIBTREE results" by GLOVES::ALLERTON (Steve Allerton 343-0205) Thu May 21 1992 22:12

    
    I'm trying to make sense out of the results returned from 
    OA$FBT_LIST_LIBTREE, e.g.
    
    $USERS:[ALLERTON.A1]AP2_FORMS.FLB;
     -- Open=1, .FLB open=1, .FLC open=0,Forms=11, Ref count=0, Channel=91
    
        ^^            ^^            ^^                           ^^
    
        What are the differences between                    Can someone
        these "Open" references?  The                    explain "Channel?"     
        documentation doesn't address the
        leftmost reference, nor does it explain
        "Channel."
    
    I'm guessing:
    
    Open=1(0)    Form Library is open(form library was opened, but is now
                                      closed)
    
    .FLB open=1  .FLB exists (When would this ever be 0 ?)
    
    .FLC open=0  There is no .FLC for this library.
    
    Thanks,
    
    Steve

744.1	Partial answer	SHALOT::NICODEM	Who told you I'm paranoid???	`Thu May 21 1992 23:15`	13
	Good guesses, Steve. The first open is whether an OA$FLO_OPEN has been done on this library. In response to your question about the .FLB, if the form library is open, the .FLB must be open; the .FLB file is necessary to get all of the standard FMS type of stuff. And, as you also stated, the .FLC will be open if there is one -- AND if it's correct to use it. In other words, you may have a .FLC, but it won't be opened if it's obsolete ("Obsolete version of .... Continuing.") Forms is the number of forms in the library. I'm afraid I can't help you on Channel... F
744.2	Channel == Internal and not very interesting?	IOSG::PYE	Graham - ALL-IN-1 Sorcerer's Apprentice	`Fri May 22 1992 11:47`	13
	Channel is probably either an RMS channel number, or an internal pointer into the DSAB list, or it's something from FMS. I don't suppose any of that would be ofinterest to anyone other than one of the developers. I guess we could look at the code if you're really interested! Graham PS Frank, so how could the first open ever be 0? If it's opened by default from the profile? Or is it 0, if the library has been closed again, but is still in cache?
744.3	Can open or close form libraries under API control	SHALOT::NICODEM	Who told you I'm paranoid???	`Fri May 22 1992 14:15`	16
	� PS Frank, so how could the first open ever be 0? If it's opened by � default from the profile? Or is it 0, if the library has been closed � again, but is still in cache? Just as the OA$FLO_OPEN causes the library to be initially opened, an OA$FLO_CLOSE will close it. There is very little in ALL-IN-1 that will cause a form library to be closed. However, any application could issue the OA$FLO_CLOSE function. In V3.0, for example, the new symbol OA$FORM_SEARCH_ORDER will list only those form libraries which are Open -- try it! Closing a form library doesn't remove it from the list; that's why, if you close a library and later re-open it, it's back in its original place in the search order -- not at the end. (And that's why V3.0 introduced some of the new capabilities it did for re-ordering the form library search order.) F
744.4	Pretty mundane	SHALOT::NICODEM	Who told you I'm paranoid???	`Fri May 22 1992 14:24`	10
	� Channel is probably either an RMS channel number, or an internal � pointer into the DSAB list, or it's something from FMS. Actually, it's the internal channel number used by FMS. When ALL-IN-1 issues an OA$FLO_OPEN, a new channel number is assigned, beginning at 0. Any application that uses FMS does the same thing, so if you're using DATATRIEVE, you could also be defining FMS channels. So as Graham says, it's not really very interesting... F
