FairCom RTG returned a different error number than the ACUCOBOL and Micro Focus file systems when you attempted to access an orphan file (missing index or data file).
Using FairCom RTG with Micro Focus:
attempting to access an orphan file (either data or index file missing) with an OPEN INPUT returned error 35 instead of 9/43
an OPEN I-O (optional) returned 05 instead of 9/43
a DELETE FILE returned 9/29 instead of 9/13
Using FairCom RTG with ACUCOBOL:
attempting to access an orphan data file (missing index file) with an OPEN INPUT or OPEN I-O returned 35 instead of 98
The logic has been modified so the ExtFH, ACUCOBOL, and Veryant interfaces return the appropriate COBOL error when a missing index is detected.
