#   -Ixxx           - Extends include file path ( limit to 8 )
#   -g              - Outputs debug info to an assembler source file (extension .a30).
#   -silent         - Suppresses the copyright message display at startup.
#   -fETI           - Extends char-type or signed char-type data to int-type
