| 1787.1 | More of a direct question. | EVTSG8::SCOTT | Does anyone look at personal names? | Fri Nov 20 1992 16:20 | 21 | 
|  | 	I will try and ask the same question in a different way.
	What has changed in V3.0 menu processing that stops the symbols/DSR 
	like OA$_FORMNAME.FIELD[KEY] being translated as a menu option? 
	(Within ;; ;;)
	It used to work in V2.3 and V2.4. Somebody somewhere must have 
	seen this before; I'm not making it up you know :-(
	It was a really really really nice, easy, quick, cheap and nasty 
	way to develop an application that could be translated into LLVs.
	I know it was/is not documented and was/is not supported, but I 
	would just like to know what happened to it and can it still be 
	done in some way. 
	Maybe I have just answered my own question? Not supported.
	Thanks for any info,
	Colin Scott

| 1787.2 | OA$_ is the symbol prefix for message | IOSG::NEWLAND | Richard Newland, IOSG, REO1-D/4A | Fri Nov 20 1992 16:40 | 10 | 
|  | 'OA$_' is the prefix for message symbols.  The implementation of these 
symbols changed in V3.0, and it may be as a result of this that your form 
with a name beginning with OA$_ no longer works.
What happens if you try get a value form the form by doing:
	<get OA$_FORMNAME.FIELD[KEY]

| 1787.3 | The GET is not a problem. | EVTSG8::SCOTT | Does anyone look at personal names? | Mon Nov 23 1992 09:41 | 23 | 
|  | 	Richard,
	Doing a <get OA$_FORMNAME.FIELD[KEY] does not cause any problem, the
	correct value is returned. 
	I know the prefix 'OA$_' is used for ALL-IN-1 message symbols. In 
	V2.3 and V2.4 ANYTHING begining 'OA$_' was evaluated at menu form
	compilation/display time, so that options defined as :-
	;;OA$_FORMNAME.FIELD[KEY];; 
	would work. This is no longer the case.
	Since <get OA$_FORMNAME.FIELD[KEY] returns the correct value, I
	don't think the change is due to symbol processing. 
	
	Has FORM processing changed to ensure that ;;OA$_something;; is 
	an actual entry in the message file?
	
	Again, thanks for any info.
	Colin.

| 1787.4 | Major surgery, so not surprising | IOSG::SHOVE | Dave Shove -- REO-D/3C | Tue Nov 24 1992 12:11 | 14 | 
|  |     The code in the symbol processor had major surgery in v3.0, so it isn't
    surprising that this has changed. The whole mechanism of "message
    symbols" (ones starting XX$_) was changed to use the new *.A1$MSG and
    *.A1$SECTION files.
    
    In particular, I found the following comment in the change history:
    
    ! 11-Jul-90   Add new routine Oa$sym_is_symmes.
    !             Add new routine Oa$sym_store_symmes
    !             and removed Oa$sym_store_msg_special
    !             and changed position of test for
    !             message syms in Oa$sym_get_symbol.
    
    Dave.

| 1787.5 | Gone with the wind? | EVTSG8::SCOTT | Does anyone look at personal names? | Wed Nov 25 1992 11:04 | 38 | 
|  | 	Dave,
	Thanks. One thing though.... are the comments from the form or 
	symbol processing routine? (<get OA$_FORMNAME.FIELD[KEY] works).
	I know message 'special symbols' are a LOT easier to create and 
	manage in V3.0 but not simple enough for a normal user to use.
	According to 'The Guide', you cannot create application specific 
	message symbol files, they have to go in the OA$_ (generic) area 
	and installed by the ALL-IN-1 manager.
	Is there any way in V3.0 where, non message symbols, user defined 
	options can now exist on a menu? I've tried :-
	;;#TRY;;
	;;@#TRY;;
	;;$TRY;
	;;@$TRY;;
	;;ENT.TXT['TEST'];;
	;;@ENT.TXT['TEST'];;
	
	;;OA$_ENT.TXT['TEST'];;        (this one was ok in V2.3 & V2.4)
	;;@OA$_ENT.TXT['TEST'];;
	
	None of these work. 
	I guess the 'FEATURE' has been 'Solved' and is gone for good...
	Regards,
	Colin.

| 1787.6 | ;;xxx;; now only works with _real_ message syms | IOSG::SHOVE | Dave Shove -- REO-D/3C | Wed Nov 25 1992 11:26 | 17 | 
|  |     The forms compiler actually does a special check specifically for
    message symbols.
    
    In v2.3 and v2.4 (I only looked at v2.4) the check was:
    
    are the first four characters OA$_?
    	if so, look up the symbol (effectively do a <GET)
    
    In v3.0, because message symbols can begin with other strings than
    OA$_, there's a new routine which checks whether the symbol is _really_
    a message symbol (oa$sym_is_symmes) - this routine does a lot more than
    just check the first four characters. The forms compiler calls this
    routine.
    
    So, the (accidental) feature has gone - sorry.
    
    Dave.
