Execution Result of Non-SQL Changes in DB2 Program Without Bind

In each execution of a COBOL-DB2 program, the timestamp of load module and package/DBRM are compared. If there is a change in the length of the variable (and no SQL change) in the program and it is compiled, then the load module will have the newly generated timestamp and on the other hand if the BIND is not performed then the package/DBRM would have an old timestamp. When this program is executed, the JCL step calling this program will fail with SQL error code -818.

If we have a COBOL-DB2 program for which SQL statement is never going to change in the future, we can pre-compile this program with option LEVEL.
