KRC0864

Common Causes

• Array index or dimension declared with a non-integer expression instead of an integer constant
• Enum or constant definition using a variable or calculation instead of a literal integer value
• Function parameter or declaration requiring an integer constant but receiving a different data type
• Incorrect syntax in array bounds, structure field counts, or other declarations expecting integer literals
• Using a variable reference or arithmetic expression where only compile-time integer constants are permitted

Troubleshooting Steps

1. 1Review the line number indicated in the alarm message and locate the exact position in the KRL source code
2. 2Identify the context where an integer constant is required (array dimension, enum value, constant definition, etc.)
3. 3Replace any variables, expressions, or non-integer values with literal integer constants (e.g., change 'index' to '10')
4. 4Verify that all array declarations use integer constants for dimensions and that enum definitions use integer literals
5. 5Check for missing or misplaced operators, parentheses, or syntax elements that may have altered the expression type
6. 6Recompile the program after corrections and verify the alarm is resolved
