CONSTANT FOR KEY MUST FOLLOW 2192
This alarm indicates a syntax error in KRL source code where a constant declaration for a key parameter is missing or incorrectly formatted according to KRL specification 2192. The compiler expects a properly defined constant value to follow the KEY keyword in the variable or parameter declaration.
Common Causes
- Missing constant value assignment after KEY keyword in declaration
- Incorrect syntax or formatting in constant definition following KEY
- Using invalid data type or format for the constant value
- Incomplete or malformed KEY declaration statement
- Missing or extra whitespace or special characters breaking the syntax rule
Troubleshooting Steps
- 1Review the KRL source code line where the error occurs and locate the KEY keyword declaration
- 2Verify that a valid constant value immediately follows the KEY keyword with proper syntax
- 3Check the KRL language specification 2192 requirements for KEY constant declarations
- 4Ensure the constant value matches the expected data type and format
- 5Correct the syntax by adding the missing constant or removing extraneous characters
- 6Recompile the KRL program to verify the syntax error is resolved
