Typically, an ILE program does not receive any function checks from an EPM program because the ILE program does not monitor for an explicit signal from the raise() function. The EPM environment generates a diagnostic message as a result of the *ESCAPE message generated by the raise() function.
When an ILE program calls an EPM C program which implicitly raises a signal (as a result of an *ESCAPE message), the ILE program can monitor for, and handle, the implicit signal raised by the *ESCAPE message.
