Subscript Expression Overflow

What does Subscript Overflow mean?

An overflow occurred during the evaluation of a subscript expression. This condition generates a Major Recoverable Fault, indicating that an out-of-range condition exists within the expression's calculation. It may also be recorded as a minor overflow fault if enabled. Calculation of subscript expressions no longer silently produces invalid results, making this fault detection more predictable.

• Calculation of a subscript expression results in an overflow condition
• Divide-by-zero error within a subscript expression
• Subscript expression producing an out-of-range result that exceeds integer limits

Click steps to track your progress.

1. 1

   Review all subscript expressions in the application program for potential overflow conditions

2. 2

   Identify specific expressions that could produce an overflow result, such as division by zero

3. 3

   Modify the logic of affected subscript expressions to prevent overflow conditions (e.g., add range checks, adjust data types)

4. 4

   Update any major fault recovery logic in the application to appropriately handle this Major Recoverable Fault
