RE: Call to HTTP_URL_P ended in error

[Naresh Mistry <naresh.mistry@xxxxxxxxxx>]

Scott, 
      Thank you very much, and yet again very grateful for your help. I will revise the rest of my code, and fix it accordingly.

Hi Naresh,

Your XML has this:

    <RBNO/>

Your EndOfElement routine has this:

   when name = 'RBNO';
      p0Rat = %subst(value:3:6);

The result is that 'value' will be 0 bytes long, and you're telling RPG to take a substring starting at position 3, and going for a length of 6. 
  That's not possible for something that's 0 long, resulting in the "Length or start position is out of range for the string operation." error.

There may be other, similar, errors in your code as well (I didn't test every single possibility.)  But, this doesn't appear to be an issue with HTTPAPI (whew!)

Hope that helps...
