Re: API - how to handle unknown receiver variable size

["David Prowak" <prowakd@xxxxxxx>]

Bruce,
I'm looking for a generalized approach for any old *DTAQ.  I'm developing
in
RPG IV and my *DTAQ in this case is non-keyed.  I'm looking to minimize 
development time where possible.  Most specifically, I'm not sure how to
code
the receiver variable using format RQDM0100 of the QMHRDQM API.  
The last few fields in RDQM0100 are repeated for each message retrieved.  
Do I define the receiver variable as VARYING?  What's the most efficient 
way (by the above definition) to get the text of each message?  

I want to build a subfile displaying the *DTAQ's contents before that data
is processed.

TIA,
Dave
