(1) In Temporary Storage Queues Data is read randomly,
While in Transient Data Queues data must be read
sequentially. (2) In a TSQ data can be read any number of
times as it remains in the queue until the entire Queue is
deleted. In TDQ data item can be read once only. To reuse
the TDQ it must be closed and reopened. (3) Data can be
changed in TSQ, but not in TDQ. (4) TSQ can be written to
Auxiliary or Main Storage, while TDQ is written to Disk.
Temporary storage is a holding place, while Transient data
is always associated with destination. The (5) TSQ name is
defined dynamically, while a TDQ name need to be defined in
the DCT. Note: An application uses TSQ 's to pass info'
from task to task, while a TDQ to accumulate records before
processing or send data for external use, such as a print
operation or other
