962.0. "PROBL: How to create new Verb" by VERS::PETROU () Fri Apr 26 1991 05:45

	Hello world,

	I need to add a deleting directive in my AM.
I would like to use the predefined Delete verb (id code =13)
but a FM intercepts my FCL request and drives me in error...

First question: Is there any way to work around this?

	Then I used a new verb "Clearinstance" (id code=200)
but even if FCL PM parses my command correctly (see bellow), the director
sends the error message: 
%MCC-E-NOTFOUND, unspported combinaison of verb, entity, partition

I ran under the bed test, and finaly it seems that the director
makes an function call, because when I ask for Call function
I obtain the same error. More over, allways under the bed test, if i ask
for a Call access the call is correctly dispatched to my entry point.

Second question: Can anybody describ the correct steps in adding a new verb,
		or tell me what goes wrong?

	Thanks for any help,
	Regards, Philippe.
		

Here bellow are; - The inp dump of FCL
		 - The MSL of my directive
		 - The dispatch Vector for my directive

What do you mean by "drives me in error..." ?

The Bridge AM implements the DELETE directive; FCL and Iconic Map PMs
handle it fine (FM dispatching is handled by Control FM, which acts a
a pass-through to Call Access).

The problem of adding a new verb to MCC is documented in many places in
this conference, along with a few short-term workarounds (the problem
will disappear in DECmcc V1.2, when Control FM is retired). Try
KEYWORD = CONTROL_FM for information...

	Hello world,

	Thanks Chris for your answer. I finaly solve my problem. I think (I am
not sur) that error was caused from by a bug in my development dictionary.
I reloaded my global entity and now it works fine...
