Are you effectively saying "don't ever use enumerations for external files and network signals" etc?Declare your enumation types so that the lowest and highest valid value comprise the lowest and highest value representable by its storage: {$mode delphi} {$z1} type tmyenum = (ea, eb, ec, emax = 255); That behaves the same both in FPC and in Delphi.
This is a completely pointless definition, since for effective use you still need to add code to check that the value is a named one.
