应用的问题：

Transactions can fail with an APCT abend, when there is a failure in a transaction attempting to load the program defined in PD.stanza.

A transaction failure with an APCT abend can be caused by any of the following:

• While loading an application or a map which is not correctly linked with the libraries.
• The requested program entry in the Program Definitions (PD) has been disabled, or the program has zero length, or an I/O error has occurred while loading the program.
• APCT abends do not occur due to internal issues, but only due to incorrect settings, or an incorrect procedure used during compilation and linking of an application.
