Enabling High Performance View Passing

Enabling the High Performance View Passing feature causes a change in the way that External Action Blocks are generated. The parameters passed, in order, are:

• IEF-RUNTIME-PARM1
• IEF-RUNTIME-PARM2
• GLOBDATA
• List of individually matched views (using the names provided in the action diagram), for example:
  • IMPORT-NON-REPEATING-GR-0005GV
  • EXPORT_CUSTOMER

The PSMGR-EAB-DATA (null array) is not passed directly as in normal view passing, because it is part of the GLOBDATA. Note that there is a change in the order of the parameters passed. Also, multiple views are passed with unique names rather than a single import/export view named W-IA or W-OA.

The following two excerpts from External Action Block stubs illustrate some of the differences in the generated stubs when High Performance View Passing is in use.
