- -- Abstract : SYSDEP - System Dependency Package
- ----------------:
- ----------------: SYSDEP provides GET, PUT, and IS_VALID_CHARACTER
- ----------------: as basic I/O routines which are defined as follows:
- ----------------:
- ----------------: GET - return the next character from the console
- ----------------: without any interpretation (all 128 ASCII characters
- ----------------: may be input with exceptions as noted by IS_VALID_CHARACTER)
- ----------------: and without echo (echo must be supplied by the user)
- ----------------:
- ----------------: PUT - output the indicated character without interpretation
- ----------------: (any valid character, noted by IS_VALID_CHARACTER, may be
- ----------------: output by PUT
- ----------------:
- ----------------: This simple pair of defined functions permits a more
- ----------------: flexible and constant I/O configuration than that
- ----------------: provided by TEXT_IO and opens up the door to future
- ----------------: tools written in Ada, such as communications servers.
- ----------------: Adaption of SYSDEP to interface thru CAIS definitions,
- ----------------: when such definitions are established and placed in use,
- ----------------: can be done at a later time. OPEN_CONSOLE and CLOSE_CONSOLE
- ----------------: must be called before the first use of PUT or GET and after
- ----------------: the last use of PUT or GET, resp.
