7-14    I8     Maximum number of observations allowed             1000 [1]      
               in one logical block (limit=9999)

               logical block.(MAXBUF)                                           
               MAXBUF must be less than or equal to 100                         
               and greater than or equal to 10                                  
                                                                                
25-30   I6     Maximum number of scratch buffers in core          200           
               must be greater than or equal to 5 and                           
               less than or equal to 400. [2]

               calculations. If this is present then a                          
               value greater than zero must be entered                          
               in columns 51-60.                                                
                                                                                
51-60   D10.3  Minimum spacing between data points for                          
               normal point calculation runs. All data                          
               closer than minimum spacing will be discarded.                   
               If this value is present then a value greater                    
               than zero must be entered in columns 31-40.                      
               This value can be overridden for specific                        
               stations and/or measurement types if NORMPT                      
               cards are present.                                               
                                                                                
NOTE [1]:  IIS imposes two restrictions on a block of observations. No block    
           can span a time period that is longer than 10*STEPSIZE, and no       
           single block of observations from the TDF can be subdivided into     
           more than 100 blocks in IIS. The number of IIS subdivisions is       
           given by: IIS subdivisions= Number of observations in a block/       
           (10*STEPSIZE/time interval between observations). If the number      
           of IIS subdivisions is greater than 100, the maximum number of       
           observations per block must be reduced.
                                                                                
NOTE [2]:  If this parameter needs to be greater than 400, please contact
           the GEODYN Group.  The error in TDF if 400 is not enough, reads
	   "Unit 21, attempt to read past end of record."
