It is RPG400 Logic means it is a compiler logic through
which system reads the primary file starting from begining
to end of file. No File operations like read/chain can be
used.System has the control of the program.

Answer / yogesh
Unless it has a NOMAIN the cycle runs -- here is the short
list of cycle stuff
it does some initialization
opens files
runs *INZSR
runs first statement
does some stuff when *inlr is on and end or return is
reached
If the F spec has a P then it automatically reads records
from that file
It can also automatically write stuff to a report and do
control breaks ...
So back a ways there were programs written with F-specs I-
specs and O-specs and the program did as the name implies -
(Report Program Generator).

Answer / svankipu
Simply put; RPG-Cycle is a default system cycle, which takes
care of all these below without having the programmer to
write the code
1)Opening a file(must be declared as PRIMARY)
2)Reading it & process it
3)Do any calculations/print reports automatically
4)Closes the files
5)Ends the program
this cycle is also called as RPG-Logic-cycle or
RPG-Life-Cycle or Default-Cycle or System-cycle.
Different people have different reservations about it's name.
