EQA1260I The CU specified for the LOADDEBUGDATA command is already an assembler or LangX COBOL CU.

Explanation

An LDD has already been done for the CU specified in the LDD command. This LDD may have been done previously by the user or an implicit LDD may have been done for the CU. This happens when a user-entered LDD is successful and, subsequently, the CU goes away and later reappears.
