z/os IMS
documentation error
This is the format of the DBE0601I message it will be added to the IMS message guide
DBE0601I
Invalid packed number in expression (&EXPRESSION) at RBA (&RBA): &NUMBER.
Reason
The WHERE clause in the CASE statement contains a packed number expression (&EXPRESSION), but the database segment does not contain a value in packed format. The Relative Byte Address (&RBA) indicates where an error occurred.
Note: A maximum of ten DBE0601I messages are printed for each WHERE clause in error.
Action
The return code remains unchanged. The WHERE clause expression that references this segment is evaluated as "not passed".
