“UNTIL” MISSING 2148
This alarm indicates a syntax error in a KRL program where the UNTIL keyword is missing from a LOOP control structure. The compiler detected an incomplete loop statement that requires proper termination with UNTIL followed by a condition expression.
Common Causes
- LOOP statement exists without corresponding UNTIL clause
- UNTIL keyword accidentally deleted or commented out in the program
- Incorrect loop syntax or malformed conditional expression after LOOP
- Missing or incorrect condition variable referenced in the UNTIL statement
- Copy-paste error resulting in incomplete loop structure
Troubleshooting Steps
- 1Open the KRL source file mentioned in the error message and locate the line number indicated by error code 2148
- 2Search for all LOOP statements in the program and verify each has a corresponding UNTIL with a valid condition
- 3Check the syntax: ensure format is 'LOOP ... UNTIL <condition>' with proper condition expression
- 4Verify the condition variable exists and is properly declared in the program scope
- 5Review recent edits or compare with backup versions if the code was recently modified
- 6Recompile the program after corrections to verify the syntax error is resolved
