     SBasic User's Manual     SBasic Version 2.7             Page 39
     Printed:  December 5, 1999
          "\n" inserts a newline ($0a)
          "\r" inserts a carriage-return ($0d)
          "\f" inserts a form-feed ($0c)
          "\a" inserts an alert ($07)
          "\b" inserts a backspace ($08)
          "\t" inserts a horizontal tab ($09)
          "\v" inserts a vertical tab ($0b)
          "\\" inserts a backslash

     For example:

          print "Hello, world!\n\r\a";

     prints the string "Hello, world!" followed by a line-feed, a carriage-
     return, and a bell.

     Run-time support for SBasic's PRINT statements relies on several
     library files, included with the SBasic distribution.  These files are
     automatically added to the assembler source file created by SBasic,
     whenever your program invokes a variation of the PRINT statement.

     You may modify the PRINT statement library routines, if desired, to
     create support for other output devices.  However, you must keep the
     names of all subroutines defined inside a library file unchanged.

     This is because the assembler source created by SBasic uses fixed
     names for library functions.  If you change the names of the library
     routines, the assembler will report an undefined label error when it
     tries to find the library subroutines.

     Note that these library files are only included if your code uses a
     PRINT statement.  You can create smaller executables by eliminating
     any use of the PRINT statement, if appropriate.

          NOTE:  Your code must issue any setup instructions necessary
          to prepare the default I/O port for use with the PRINT
          statements.  For details on setting up the 68hc11's SCI,
          consult the section below, "Character I/O on the 68hc11."

     SBasic supports a version of the INKEY() function.  You can use
     INKEY() to receive characters from a default input device, based on
     the target system.  For the 68hc11, this is the SCI.  For the 68hc12,
     this is the first asynchronous serial port, similar to the SCI.

     Unlike the INKEY() function in traditional Basics, SBasic's version
     does not expect or allow an argument.

     If no character was received from the console, INKEY() returns 0.  If
     a character was received, INKEY() returns a value containing the
     character in the low eight bits; additionally, INKEY() sets bit 8 of
     the returned value.  Setting bit 8 allows your program to distinguish
