949.0. "How to build a Presentation Module ?" by RIVAGE::BOSSER () Wed Apr 24 1991 11:52

Hi,

I am just beginning to build a Presentation Module (an Agent PM) and 
I am looking after information on the subject.
There is nothing about it in the MM Programming.


To see what happens, I have just developed a very simple entry point 
(containing just a prinf, no MCC_CALL, no MCC routines)
for my Agent PM, compiled and linked it with MCC_KERNEL_SHR.

I have defined the following logical :
$DEFINE/JOB MCC_AGENT_PM TAEC$ENGIN:[BOSSER.AGENT]MCC_AGENT_PM.EXE

Then I have tried to call my Agent PM using :
	$ manage/enter/presentation=mcc_agent_pm
Unfortunately, it doesn't work !!!
I receive the error message :

%LIB-E-KEYNOTFOU, key not found in tree
%MCC-E-FINDUSYM, failure finding universal symbol !AS in shareable image !AS



Does it exist a documentation explaining how to develop a Presentation Module ?
What entry point to offer to be called by the MCC Kernel ?
How to link a PM ? 
Does it exist a very simple example ? (not the full Iconic Map PM code !)


Thank in advance for your help.

You can do it, but as you have found out we do not yet support an open
(documented) interface to writting a PM. This was done since the PM
has a number of more constraints/rules that need to be clarified
and documented before having external parties develope PMs.

If you really need a PM to do something, and the work isn't already planned
for the existing PMs I am sure something can be worked out to get you the 
information you require. I would prefer not to place it here ,since 
it isn't officially supported yet (a number of groups/companies though are already off
and working on PMs with assistance from our group).
