QMHSNDPM - Call stack entry parameter

["Lim Hock-Chai" <Lim.Hock-Chai@xxxxxxxxxxxxxxx>]

I'm a bit confuse about the Call Stack Entry parameter in QMHSNDPM api
and hope somebody can help me with it.  In ibm doc, this parameter is
declared as char(*).  See below:

QMHSNDPM api Required Parameters Group:
1	 Message identifier	                   Input	 Char(7)

2	 Qualified message file name	             Input
Char(20)	
3	 Message data or immediate text	       Input	 Char(*)	
4	 Length of message data or immediate text	 Input
Binary(4)	
5	 Message type                       	 Input	 Char(10)	
6	 Call stack entry	                         Input	 Char(*)
or Pointer	
7	 Call stack counter	                   Input
Binary(4)	
8	 Message key	                         Output	 Char(4)	
9	 Error code	                               I/O
Char(*)
 
 
	
In most case, that means that there should be another parameter that
caller must use to tell this api how long this Call Stack Entry
parameter is.  But, I'm not seeing this paramter, am I missing
something?  I google the web and most of the prototype I found has been
declaring this parameter as 10 A.  Here is one example
