RT-11 IND - Curious Error Message

I have been asked to modify a medium sized IND control file in order to upgrade a system to Y2K compliance. The specifications call for testing a specific file on the old data diskette and replacing it with a new version. In the course of making the changes, I have had a problem! Rather than post the complete IND control file, I have retained the statements which are causing the problem. And they have been modified so as to be generalized. Please be aware that while these statements serve no useful purpose by themselves, all but their essence was removed so as to produce this example in which the problem still appears. Most are from the original control file and a few are present due to the new specifications. So PLEASE don't just respond that the control files shown serve no useful purpose - 99% is missing and only the part which causes the problem has been retained. Someone taking a quick look at the problem might dismiss it as useless. I have 2 questions: (a) Is my understanding of IND incorrect and am I using IND in an incorrect manner? (b) Is there a bug in IND which is causing the problem? I have attached 2 files. The first is the minimum which causes the problem. The second provides a control test situation which does seem to work at first, but not under the conditions which are present in the "minimum" test file. Anyone out there who is still working with RT-11? Sincerely yours, Jerome Fine
