I have a compoents input record format with a field set to NULL, like,

record

string(3) INPUT = NULL;

end;

Comp A -----FlowAtoB---------> Comp B

The above record format is the FlowAtoB. I can understand that this sets the value of INPUT to null. But, In case if i have value for this from previous component A, how this will behave?

I'm not able to understand clearly the use of this from the help document.

It is the default setting for your INPUT.
There is nothing wrong with it.
When component A will send the information to B it will behave just fine, as far as I'm concerned.

Look at this example from my grpah that I'm working right now:

string(30) salesperson = NULL("");

When I send data it works ok.

Try adding the brackets and quotation marks, but I think it was by default there.
Hope this helps

  • Thanks Marcin. So, in case that particular field like your salesperson has a value from previous component. The value is same here in my next one. In case, the field is empty, it'll replace a null. Correct me if i'm wrong. – Harbinger Dec 16 '14 at 11:16

    Yes, this is exactly as I understand it, and it works for me. – marcin Dec 16 '14 at 11:19
