Hello
I have more than 130 milion records in a sequential dataset Flat file
What is the best way to search for records in the FLat file?
Can i convert flat file into some indexed file to search records efficiently? |

Two-file match. There's an example as a "sticky" on the first page of topics in this forum.
You may want to consider doing the match using PGM=SORT and JOINKEYS to extract the data you need to then process in your COBOL program. |
