 39    Notes
 40 
 41    This version of the CD database application has been written
 42    using the information presented in the Terminals chapter.
 43 
 44    It is derived from the shell script presented in the Shell
 45    Programming chapter. It has not been redesigned for the C
 46    implementation, so many features of the shell original can
 47    still be seen in this version.
 48 
 49    There are some problems with this implementation that will
 50    be resolved in later revisions:
 51 
 52    It does not deal with commas in titles.
 53    It has a practical limit on tracks per CD to keep them on screen.
 54 
 55    The program deliberately uses the standard input and output
 56    file streams. It does not deal with re-directed input or
 57    output explicitly.  */

 39    Notes
 40 
 41    This version of the CD database application has been written
 42    using the information presented in the Terminals chapter.
 43 
 44    It is derived from the shell script presented in the Shell
 45    Programming chapter. It has not been redesigned for the C
 46    implementation, so many features of the shell original can
 47    still be seen in this version.
 48 
 49    There are some problems with this implementation that will
 50    be resolved in later revisions:
 51 
 52    It does not deal with commas in titles.
 53    It has a practical limit on tracks per CD to keep them on screen.
 54 
 55    The program deliberately uses the standard input and output
 56    file streams. It does not deal with re-directed input or
 57    output explicitly.  */
