Primary File is the one which uses the RPG logic cycle. It
is defined in the F spec as:
FABPF1 IP E Disk
Here, ABPF1 is primary file.
For a primary file we cannot use any operations like Read,
Reade, Chain etc. It automatically reads from the 1st to
the last record and executes the program from the 1st to
the last line. A program can have only 1 primary file
defined.
Secondary file is exactly like the primary file in
functioning except that the program starts processing the
secondary file only when the EOF is found for primary file.
A program can have multiple secondary files defined in it.

Can we create 300 logical files based on a single physical file using the CRTLF command only once?.
