Hi Simon,<div><br></div><div>Thanks for the consideration.</div><div><br></div><div>It's a little difficult, though, to give such a flannel answer to a customer, when the manual says one thing and then the supporting code doesn't exist.</div><div><br></div><div>I had walked through how the callback might might be constructed with the customer and then put together a simple demo script to help them program things in the future.</div><div><br></div><div>Slightly red faced when I got rejected by the terminal!</div><div><br></div><div>Can someone from IBM say which callback parameters are actually valid and supported? I'm programming against 4.2.3.8 in this instance.</div><div><br></div><div>Cheers,</div><div>Luke.</div><div><br></div><div><br><br><div class="gmail_quote"><div dir="ltr">On Mon, 23 Apr 2018, 17:08 Simon Thompson (IT Research Support), <<a href="mailto:S.J.Thompson@bham.ac.uk">S.J.Thompson@bham.ac.uk</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
