You can gather data for your reports by joining data sources using the JOIN command, merging the contents
of data structures using the MATCH command, or concatenating data
sources using the MORE phrase, and reporting from the combined data.
- The JOIN command creates a new parent-child structure from multiple data sources.
- The MATCH command creates new data records by combining records from two or more data sources, based on common sort values.
- The MORE command appends output from multiple data sources.
