Trigger parameter prototypes

["Smith, Nelson" <NSmith@xxxxxxxxxxx>]

I'm having trouble converting my trigger programs over to using prototypes
rather than a PLIST.

How do you specify the first parameter for a trigger in a prototype?  If I
use an asterisk for a pointer,  how do I define the datastructure to start
at that pointer location?   Since the second parameter gives us the size of
the first parameter, can that be used to declare the size of the first
parameter?

Given D-specs of:

D Buffer        DS
D BufferLength  S                       10I 0


a PLIST of:

C       *ENTRY  PLIST
C                       PARM            Buffer
C                       PARM            BufferLength

works just fine, but a prototype and interface of:

D TriggerPgm            PR              EXTPGM('MyTrig')
D                                  *    CONST
D                               10I O   CONST

D TriggerPgm            PI
D  Buffer                          *    CONST
D  BufferLength                 10I O   CONST

doesn't.   Do I have to declare the buffer at the maximum size it could be
(32,767 bytes) or is there some way to declare it based on the second
parameter?
