Use the following fields in the problem determination area (PDA) as modifier keywords except for common filter services, which neither employ an ESTAE nor use a PDA:

• Failure-related module
• Most recent calling function
• Return code
• Reason code.

The failure-related ISPF log entry's FEEDBACK field contains the PDA information. See Figure 1 for a sample entry containing PDA information. See DASD common services—problem determination area (PDA) for a description of the PDA contents.

1. Specify the contents of the PDA fields as modifier keywords.
   Example: If the module name is IGBDIS01, the return code is 10, and the reason code is 038, specify the modifier keywords as:

   IGBDIS01 RC10 RC038

2. See Table 1.
