keyword inheritance question [message #87167]

Say I am writing a program (myPro) that uses two other programs (libPro[1-2]) and want to be able to let the user know that the keyword they gave does not exist.

Ideally, I would use _STRICT_EXTRA to do this. I cannot in this case, though.

As a solution, I can put the keywords of libPro1 into the keyword list of myPro. Alternatively, I could just bite the bullet and use _EXTRA, letting unused keywords fall through quietly.

Any advice/preferences/pet peeves on this?

IDL> myPro, /Key1, /Key2

-----------------
pro libPro2, KEY2=key2
end

pro libPro1, KEY1=key1
end

pro myPro, _EXTRA=extra
libPro1, _EXTRA=extra
libPro2, _STRICT_EXTRA=extra ;Must use _EXTRA!
end
