Functionality
This module has been created as an example for the interface and designof Search help exits inSearch help.
All the interface parameters defined here are mandatory for a functionmodule to be used as a search help exit, because the calling programdoes not know which parameters are actually used internally.
A search help exit is called repeatedly in connection with several
events during the F4 process. The relevantstep of the process is passed on in the CALLCONTROL step. If the moduleis intended to perform only a few modifications before the step,CALLCONTROL-STEP should remain unchanged.
However, if the step is performed completely by the module, thefollowing step must be returned in CALLCONTROL-STEP.
For more detailed information please refer to the documentationdescribing the concept of the search help exit.
The module must react with an immediate EXIT to all steps that it doesnot know or does not want to handle.
