Doesn't surprise me. We get blank and zero overlays all the time. What I really needed, and have, is a good way to explain what is happening and how he is misunderstanding what is needed in COBOL, according to the manual. I am not a COBOL programmer. And I explain things is assembler ways, which sometimes confuse them. And they often want me to make COBOL work the way that they think that it should or explain why it doesn't. I don't think that way. So I get "short" with them. I'm not good with children, either. On Sep 11, 2013 7:00 PM, "Hardee, Chuck" <chuck.har...@thermofisher.com> wrote:
