KUKA Robot KRC0796 - EXPRESSION AFTER RETURNING INSTRUCTION MISSING 2132
EXPRESSION AFTER RETURNING INSTRUCTION MISSING 2132
This syntax error occurs when a KRL program contains a RETURN instruction that is not followed by a required expression or value. The compiler expects an expression after the RETURN keyword to specify what value should be returned from the function or program block.
Common Causes
- RETURN statement written without a following expression or value
- Missing variable or constant name after RETURN keyword
- RETURN statement placed at end of line without proper expression syntax
- Incorrect use of RETURN in a VOID function that should not return a value
- Copy-paste error or incomplete code editing leaving RETURN incomplete
Troubleshooting Steps
- 1Locate the line number indicated in the error message within the KRL source file
- 2Examine the RETURN statement and verify it includes a valid expression or value after the keyword
- 3Confirm the return type matches the function signature definition
- 4Add the missing expression, variable name, or constant value after RETURN
- 5If the function should not return a value, replace RETURN with appropriate exit statement or remove it
- 6Recompile the KRL program and verify the syntax error is resolved
