 SUKEYCOUNT - sukeycount writes a count of a selected key    

   sukeycount key=keyword < infile [> outfile]                  

 Required parameters:                                        
 key=keyword      One key word.                                 

 Optional parameters:                                        
 verbose=0  quiet                                            
        =1  chatty                                           

 Writes the key and the count to the terminal or a text      
   file when a change of key occurs. This does not provide   
   a unique key count (see SUCOUNTKEY for that).             
 Note that for key values  1 2 3 4 2 5                       
   value 2 is counted once per occurrence since this program 
   only recognizes a change of key, not total occurrence.    

 Examples:                                                   
    sukeycount < stdin key=fldr                              
    sukeycount < stdin key=fldr > out.txt
