Data Interchange

Data written to a spool file can be read forwards or backwards.

A CA Spool spool file can be created and written like a sequential OS data set without requiring space allocation through the JCL or dynamic allocation.

The spool file can subsequently be read using the Call Interface available to applications, or through JCL SUBSYS interface.

Because CA Spool allows any task or job to read any spool file (assuming certain file attributes are known), applications have the option of using CA Spool as an interim depository for data collection.
