As I said, it's in the TSO/E Customization book. The edition I have here is SA32-0976-02 z/OS V2R2 TSO/E Customization. It's in Chapter 43 "Routines and interfaces to support a REXX compiler". But I don't think the exact format of the eyecatcher is documented there or anywhere else. The Customization book is about customizing TSO/E rather than the REXX compiler. This book is agnostic about the compiler; you can in theory write or buy one from anywhere, and it might have a different eyecatcher from IBM's, or none at all. For that matter, there is nothing I can see to require that the CEXEC file must begin with executable code. When TSO/E runs a CEXEC, it doesn't branch to the start of the CEXEC, but rather it calls the routine whose name is in columns 13-20. That routine invokes the CEXEC code, but that code could be in Java bytecodes or any other scheme, as far as I can tell.
