Storage, Scratch, and Queue Management

Pseudoconversational programming demands techniques that efficiently pass data from one task to another. You should choose the method or combination of methods best suited to the needs of your application. You can choose different methods based on the following considerations:

Length of time that the data is needed
Availability of the data to other users
Data recoverability
System resources used
Network resources used
Number of variables

CA IDMS provides these services for managing online variable storage:

Storage pools manage short-term variable-storage resources and pass data from one task to another
Scratch records pass temporary data between tasks running on the same logical terminal
Queue records pass more permanent data from one task to another
The terminal buffer passes very small amounts of data between tasks running on the same logical terminal.
