Specifying a keyed sequence access path without using DDS

 

The dynamic access path function of the Open Query File (OPNQRYF) command allows you to specify a keyed access path without using data description specifications (DDS).

If an access path that can be shared already exists, the system can share it. If a new access path is required, it is built before any records are passed to the program.

• Example 1: Specifying a keyed sequence access path without using DDS
  This example shows how to arrange records using one key field.

• Example 2: Specifying a keyed sequence access path without using DDS
  This example shows how to arrange records using multiple key fields.

• Example 3: Specifying a keyed sequence access path without using DDS
  This example shows how to arrange records using a unique-weight sort sequence.

• Example 4: Specifying a keyed sequence access path without using DDS
  This example shows how to arrange records using a shared-weight sort sequence.
