As long as the interface has not changed, you will not need to recompile.

You need to create a current listing your procedures. then when you add a
new procedure, your current becomes your previous and your new current is
at the top.

This will result in two signatures. Any program recompiled will get the
current signature. The older programs will use the previous signature.

STRPGMEXP PGMLVL(*CURRENT)
EXPORT SYMBOL('XVUSRQ_Open')
EXPORT SYMBOL('XVUSRQ_Close')
EXPORT SYMBOL('XVUSRQ_Put')
EXPORT SYMBOL('XVUSRQ_Get')
EXPORT SYMBOL('XVUSRQ_GetNumberOfMessages')
ENDPGMEXP

STRPGMEXP PGMLVL(*PRV)
EXPORT SYMBOL('XVUSRQ_Open')
EXPORT SYMBOL('XVUSRQ_Close')
EXPORT SYMBOL('XVUSRQ_Put')
EXPORT SYMBOL('XVUSRQ_Get')
ENDPGMEXP

I've learned that I should add new exports only/always to the end of

that, by doing so, programs that call existing procedures in the
binder source do not need to be recompiled. Correct?


Add a SIGNATURE to the STRPGMEXP line of your binder source.

That way programs that bind to the service program won't need to be
recompiled (as long as new procedures are always added to the end of the
binder source).

IBM i on Power Systems: For when you can't afford to be out of business!

I'm riding a metric century (100 km / 65 miles) in the American Diabetes
Association's Tour de Cure to raise money for diabetes research, education,
advocacy, and awareness. You can make a tax deductible donation to my ride
by visiting https://lsteml.diabetessucks.net. My goal is $6000 but any
amount is appreciated.

See where I get my donations from ... visit https://lsteml.diabetessucks.n
et/map for an interactive map (it's a geeky thing).

I may have diabetes, but diabetes doesn't have me!
