Re: MAIN and LR

Barbara

Help me out here - I've always thought leaving *INLR *OFF means that on another call to the program, variables will have the values they had when the program ended before. Is this different with the MAIN keyword - remember, we don't compile to 7.1 (blushing!).

Thanks
Vern

I am beginning to use the MAIN keyword in new programs. Do you still
need to set on *INLR before exiting the program, when MAIN is used to

manual or documentation that gives me the answer.

No, you don't need to set on *INLR. Setting on *INLR controls the RPG
cycle, but a linear-main module doesn't use the RPG cycle.

The linear-main procedure will just end when it gets to the end of the
calculations. You _can_ set on *INLR if you want, but it won't do any of
the cycle-related things like closing files.

Here is a comparison of a cycle-main module and a linear-main
module.http://publib.boulder.ibm.com/infocenter/iseries/v7r1m0/index.jsp?topic=%2Frzasd%2Fsc09250802.htm

Conceptually, a linear-main module is much more like a NOMAIN module
than it is like a cycle-main module. The only way it is similar to a
cycle-main module is that it can be used as the program-entry module for
a program.
