Answer / prima krishnan

Data areas are objects of type *DTAARA that we can create
and delete at will..A data area that can be used to store
informations with a name,but without any structure...
Dataqueues are permanent objects(type
*DTAQ) that can be used for asynchronously communicating a
strem of values between programs or jobs.....

Answer / rajesh binani

A Data Area and a DataQ are not having similar features,
but the length of Data area is limited to 1024chars and the
DataQ can have a length of 64512chars.

A DataQ is erased as soon as the data is retrieved from it.
Whereas the data area can have the data stored in it until
the user opts to clear it. In DataQ one had variable for
arrival date,time, the sender id, and the key(in case of
keyed dataq)- this is an advanced feature in DataQ

Hope this helps.
