When CCP trace is active and the option of recording to the RTL/RTA tape is selected, the CCP trace recording segment CIJF will add each block to the PI list as it is filled. The block contains an enter expansion to CIJF Transfer Vector 5, which operates as a normal application program to write the core blocks to the RTL/RTA tape.
If the write to the RTL/RTA tape option was not selected, no output is generated, but on any dump that occurs, the wrap around trace core block will appear in the dump with the header CCP TRACE BLOCK. This block will contain a record of the last 40 activities traced.
The only console messages output by CCP trace are replies to input commands. For more information about these console messages, see Messages (System Error and Offline) and Messages (Online).
