DESIGN CONSIDERATIONS FOR TSQ - IBM Mainframe

The TSQ placed is more advantageous over the TDQ. Some of the advantages are efficiency and convenience. The only disadvantage is that the TSQ in the main storage is not recoverable after a system crash or transaction abend. TSQ can be used for passing data among transactions, which is especially useful in the pseudo-conversational mode, because data can be passed from one transaction to the other transactions. Review and correction of multiple order entry screens can be accomplished by saving the screen data in TSQ and later retrieving them for review and correction.
