I am having trouble figuring out how to fix this error in Natural Adabas. I am just starting out with Natural on a very old version and the problem I keep running into trying to run most of the existing programs written by previous developers is that I keep getting this error.
NAT3176 Error in call to Adabas subroutine or in inverted list.
So I have attempted a very basic program of my own with the same result (see below). Does anybody know how to resolve this problem or what steps can be taken to debug?
My first thought is that the STUD list does not exist even though there is a DDM for it. Is there a way I could verify that it exists?
My test program is as follows:
0010 DEFINE DATA 0020 LOCAL 0030 1 STUD-VIEW VIEW OF STUD 0040 2 STUDNO 0050 END-DEFINE 0060 READ STUD-VIEW BY STUDNO 0070 DISPLAY STUDNO 0080 END-READ 0090 END
