Parameters for Ties 
                   ------------------- 
Files td/ns, td/nl, tu/ns, tu/nl contain the source parameters 
for printing ties.  See files for meaning and organization of  
parameters.  
   
&dDInvert&d@ is a program which perports to make an approximate version  
of tu files from td files  
   
The object file contains all the paramters.  The first record in 
the file contains parameters for the case where the distance between 
notes exceeds 340 dots.  The next 161 records contain the parameters 
for the distances 20 to 340.  There are four times twelve or 48  
parameters in each record.  The four large groups of parameters  
(12 each) are derived from the four files listed above (in the 
same order).  The printing program must determine the following: 
   
   1. Tips up or tips down      \  
                                 This will determine proper
   2. Note on space or on line  /                  large group
   
   3. Distance between notes 
   
   4. Stem out of the way or in the way  
   
   5. Tie in free space or in constrained space  
   
If the distance is 340 or greater, the first record contains 
the necessary parameters to print the tie.  Otherwise, record  
(d / 2 - 8) must be sought, and the proper parameters withdrawn.
