I wouldn't think there would be any way that could modify the original array element's value. Usually the array elements aren't empty upon returning, they just contain incorrect data. In one instance every element in the array was replaced with the same value, the PK! More commonly, only the other 3 numeric fields have been replaced. This causes an error when the application attempts to store the data back to the table because the PK's value is too large for the other numeric fields. In fact, that error is often the only symptom that something has gone wrong. What could assign the value from Case(2) to all 14 or so elements in the Case() array? Or even to the other 3 numeric elements?

Hi Jim

An array is in a sense a collection of variables, not a variable itself. It gets confusing to see m.case = m.case(2), because this will assign a single array element to the entire array. Just a suggestion: don't put mdot on arrays because they're a different animal. By not putting mdot on them, they stick out further from the surrounding code.
