Q

Reading a flat file

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.
