 1-6      A6           FREEZE: Allows the user to 
                       control observation editing
                       and arc parameter contribution
                       during various iteration

 7-8      I2           Arc iteration after which the       999
                       editing of observations will
                       freeze.

 9-10     I2           Global iteration for which the       1
                       option on columns 7-8 will apply 

11-12     I2           Arc iteration before which the       0
                       arc parameters will not contribute
                       to the normal matrix.  This option
                       is usefulfor dynamic crossover
                       processing where a number of inner
                       iterations is needed for the best 
                       crossover location extimate 



IF CARD OMITTED:  There will not be any editing freeze nor
                  normal matrix changes.

NOTE:  A blank FREEZE card will not cause editing freeze 
       nor normal matrix changes.
