[Statically adding Host Command Environments] Yes, you can do this without having to run code ahead of time. But there are some problems with the whole REXX environment, including HCEs. Most of them have to do with the "integrated into TSO/E" vs "not integrated into TSO/E" split. I believe most of this strange design is fallout from the time when invoking APF authorized programs first became usable under TSO/E. An HCE such as the proposed FTP one might well want to add its own routines to handle I/O or message processing, but those services are unavailable if the REXX environment is integrated into TSO/E. There is always the choice of initializing an environment that is not integrated (even when running unser TSO/E), but then the TSO/E services are not available. One has the choice of these or those useful features, but not both.
