We upgraded to MPE iX 5.0 two weeks ago, and experienced
two problems related to the upgrade:
 
.       A Cobol '85 program that had not been changed in two
        years failed when it attempted to update a single record
        parameter file saying either bad mode or end-of-file.  I
        don't know why the code ever worked: the file was opened
        input-output sequential file, the first record was read
        using "READ", and at the end of the program it was
        updating using "WRITE".  Since I viewed the code as the
        real problem and I ran out of time, I changed the
        "WRITE" to "REWRITE" and had no further problem.
 
.       We had to also update the OCS Express software, and in
        the process of doing this, the calendar was affected.
        I was told we should have "reloaded it" by the person
        who didn't do it.  I don't know the root cause of this
        problem, but it caused several jobs to start that
        should not have.
 
Overall, we are quite pleased.
