KUKA Robot KRC0729 - CHARACTER OR INTEGER CONSTANT EXPECTED 2065

CHARACTER OR INTEGER CONSTANT EXPECTED 2065

This syntax error indicates that the KRL compiler encountered an invalid or missing character or integer constant in the source code. The compiler expected a properly formatted constant value (such as a numeric literal or character string) but found something else instead, typically a malformed expression or missing operand in @P1@.

Common Causes

  • Missing or malformed numeric constant (e.g., incomplete number like '5.' without digits after decimal)
  • Invalid character constant syntax (e.g., unclosed string literal or improper quote usage)
  • Incomplete or corrupted expression where a constant value is required
  • Typo or syntax error in variable initialization or array index declaration
  • Missing operand after an operator (e.g., arithmetic or comparison operator without following value)

Troubleshooting Steps

  1. 1Open the KRL program file and locate the line number indicated in the error message near @P1@
  2. 2Review the syntax around the flagged location for missing or malformed numeric or character constants
  3. 3Verify that all string literals are properly enclosed in quotes and all numeric values are correctly formatted
  4. 4Check for incomplete expressions, missing operands, or truncated constants in assignments or declarations
  5. 5Compare the syntax against KRL language documentation to ensure compliance with constant declaration rules
  6. 6Correct the syntax error, save the file, and recompile the program to verify the alarm is resolved
