Block <n> / offset <m> not found in file <o>

This message is displayed during program execution. The return from a subroutine cannot be executed. Processing is faulty.

The most likely cause of this message is that the main program has been overwritten by a parallel program transfer, so that the return address from the subroutine back to the main program can no longer be found.

Execution of the program should be aborted. Check program structure.
