Cannot write the variable

What does 12329 mean?

An attempt to write a KAREL program variable to an opened file failed. This IO_STATUS error indicates a problem during the variable writing process, possibly due to data incompatibility or file access issues. The program will abort if the file_id is invalid.

Common Causes

  • Attempting to write a variable to a file that is not properly opened, or opened without write permissions.
  • The variable data type or format is incompatible with the target file or the specific write operation being used.
  • Insufficient permissions on the storage device to complete the write operation.

Repair Steps

  1. 1

    Verify the file_id corresponds to a correctly opened file with explicit write permissions.

  2. 2

    Ensure the KAREL variable being written is valid and compatible with the file format and the write routine.

  3. 3

    Use the KAREL command READ file_id(cr) to clear any existing IO_STATUS error condition.
