Sample exit that supplies a user key

Note: This sample only illustrates the exit functionality and the corresponding return code. It does not actually generate an encryption/decryption key.

The CTDX029K member in the IOA SAMPEXIT library contains a sample exit for returning a 24-byte key. The key would be used by the CDAM Encryption routine for encryption and decryption.

It also communicates with CDAM (via a return code for the INIT call) not to call the exit for processing blocks.
