8 Volume Having got the cassette recorder connected to the computer the only remaining thing to do is to set the playback volume on the cassette recorder to the correct level. With the BBC Microcomputer the cassette volume control setting is not critical. However, a special procedure for setting the volume control correctly is incorporated into the first program on the tape. Running the WELCOME programs Note:
If your machine is fitted with a Disc, Econet, Teletext or IEEE interface and you wish to use a cassette, you must first select the Cassette Filing System by typing *TAPE RETURN This command should also be typed in (if your machine has one or more of the above interfaces) directly after use of BREAK or CTRL BREAK . In some cases, very long cassette programs may not run because of the small amount of extra memory used by the Disc and Net filing systems. To overcome this, follow the *TAPE RETURN command by:
PAGE = &E00 RETURN NEW RETURN (See chapter 33 for explanations of PAGE and NEW .) If at any time you wish to return to the Disc or Econet filing systems, press BREAK or CTRL BREAK , or type: *DISC RETURN or *NET RETURN Bearing in mind the above note, the WELCOME programs can be run by typing in CHAIN "WELCOME"
