Q

Reading a flat file

This Content Component encountered an error

We can create an external described physical file using keys. In the program if we read this file, it will be read in keyed sequence. I now have a flat file (length 132 -- created using CRTPF command). I want to read that file in my RPG program in a particular sequence. Is it possible to read a flat file in sequence (using keys), and if yes how?

If you want to read the flat file in a particular sequence, then you could created a keyed logical file over the single column used in the definition of the flat file. Another possibility would be to use OPNQRYF and specify the single column as the keyfld.
