<P> Data General's CLI under their RDOS, AOS, etc. operating systems, as well as the version of CLI that came with their Business Basic, uses only / as the switch character, is case - insensitive, and allows "local switches" on some arguments to control the way they are interpreted, such as MAC / U LIB / SABC $LPT / L has the global option "U" to the macro assembler command to appemd user symbols, but two local switches, one to specify LIB should be skipped on pass 2 and the other to direct listing to the printer, $LPT . </P> <Table> <Tr> <Td> </Td> <Td> This section does not cite any sources .
