      ERR_STRUCT,      -> Structure version not supported or not found. 
      ERR_FAILED,      -> General failure 
      ERR_FILE,        -> File error, eg file not found.
      ERR_DATA,        -> There is an error in the given data.
      ERR_SEARCH,      -> A search routine failed to make a match.
      ERR_SCRTYPE,     -> Screen Type not recognised.
      ERR_MODULE,      -> Trouble with initialising/using a module.
      ERR_RASTCOMMAND, -> Invalid raster command detected.

->* exec definition but CHIP is renamed to VIDEO (displayable memory) and

->* NO_EXPUNGE are also unused.
