Re: Trigger techniques

Which is why in my trigger mediator the entrance procedure is a C module (4
lines of code) that calls an RPG procedure so everything is completely
recursive.

In version at our company (We are at 6.1) I have eliminated the C module and
just used the Main keyword but for anything earlier you need the C module.

The only possible issue with this...

If your actual trigger does an update to another file that also has
the gentrigger attached, the process will blow up because RPG doesn't
allow recursive programs.

Unless,
--- the gentrigger activation group is *NEW, which would be a horribly bad
idea.
--- your on 6.1 or higher and gentrigger is a linear-main program that
doesn't use the cycle.

Otherwise, your gentrigger should really be a ILE C or ILE CL program.
( you could also have just a C or CL entry point with RPG modules in
an ILE program)

Hello Jon,

I use a generic rpg trigger (called gentrigger) which determines the
name of the actual trigger program from the file name and calls it
with the standard parms. The actual trigger program is compiled
*caller. I also have a file which contains the trigger name and
whether to restart it or not.

When I need to replace a trigger, I promote the change and input a
flag in the file that says reload. the next time it fires, it checks
the file, sets on LR and changes the flag back.

Anyone care to share what they do to facilitate being able to bring a
new version of a trigger program into use.
