An assembler routine must be released using the same language that fetched it. An ILC module which has been loaded using CEELOAD cannot be deleted. An ILC module which has been fetched using CEEFETCH can be released using CEERELES. COBOL, C, C++, and PL/I can only CANCEL or release the assembler routine if there is no ILC with PL/I and Fortran in the target load modules.
