All child records for a specific parent/relation

pAll_For_Parent_Relation ;
        Integer Pre_Message ;
        Integer Main_Message ;
        Integer Post_Message ;
        String  Parameter ;
        Integer Stop_On_Error ;
        Integer Busy_Counter ;
        Integer Parent_File ;
        Integer Relation_Code ;
        String  Parent_Value ;
        Integer Recurse ;
        Returns Integer

Process all child records for a given parent in a given relationships. The pre-messages is executed once prior to processing the children. The post message is executed after all children are processed.

The parameter is passed to pre, main and post. Main should return 0 for success, non zero for error.

Stop_On_Error indicates whether an error should stop processing or whether it should continue processing. Valid choices:

• 0: Report errors, do not stop
• 1: Do not report errors, do not stop
• 2: Do not report errors, but stop
• 3: Do report errors and stop

Busy_Counter indicates the number of the busy counter to update; -1 indicates no busy counter to be updated.

The return value is either the number of records processed, or a negative number indicating an error.

This message is processed in/send to the data dictionary of the child file.

If the Recurse parameter is True, the message will be processed for all grandchildren by any relation. However, only the Main_Message will recurse. If you need to execute pre- or post-messages on other levels, you will need to perform the recursion in your own main message.

All child records for a specific parent

pAll_For_Parent ;

        String  Parent_Value ;
        Integer Recurse ;
        Returns Integer

Identical to the message pAll_For_Parent_Relation, but this works on all the relationships to the parent. The Init_Message is send prior to all the relationships, the Pre_Message is send at the start of the handling of every specific relation. Likewise, the Term_Message is send at the conclusion of all the relationships, whereas the Post_Message is send at the end of every set of related records

All child records for a specific parent by a specific relation

pAll_Children_Relation ;

        Returns Integer

This message processes all the child records in the specified child file for the current record in the specified buffer, using the specified relationship. This message is effectively identical to pAll_For_Parent_Relation, except that this message is issued to the parent data dictionary rather than to the child data dictionary.

Buffer_Id should contain the ID of the buffer that holds the current record (0 = global buffer). The child file specifies the number of the file in which the children should be processed.
