PB 2022 1900

I don't think its possible (I tried) but maybe someone has a way.  Oracle came out with Named Notation quite some time ago and I want to use it in PB.  Something like this:

     FUNCTION Long EndUnload (Long anSourceIdx => SourceIdx) RPCFUNC ALIAS FOR "IcTrx.EndUnload"

Anyone have a trick to support this?

Thanks again,

Chris Craft

I don't know a way to do this with Powerbuilder. But you could write a wrapper function or an overloaded funtion in Oracle.

Thank you René - I will just add the argument in the middle so I don't need to specify all the other 'Default' arguments. Maybe Appeon will add this as a new enhancement one day.

You can always request for an enhancement. Of course this doesn't mean it will be implemented.

Hi.

Creating a synonym is an option?

Named Notation means to specify the arguments name in function call using "=>". So I think a synonym is not usable here.

You may be right. I thought the issue was about using ALIAS FOR "IcTrx.EndUnload"...

Correct - I am trying use "=>" in the declaration for PB. This is a great feature because it allows us to specify the pieces we need and not have to populate every argument in its correct position. If we add a new argument to the procedure it typically gets added to the end but if the PB code needs it I am then forced to include every argument in between.
