\ap\pa

Note:  
           The rows can be referenced to by using commas for enumeration
           and a double-dot for ranges, e.g. @1..5,10,15 designs the rows
           1 to 10, the row 10 and the row 15. 
           The command will expand the table, i.e increase its number of
           rows, if the row given in the command line exceeds the
           limits of that table. The command CREATE/ROW may be used to add
           rows at any position of the table.	   
           The descriptor HISTORY will not be updated by this command. 	   
	   Instead of write/tab the short form: 
	   {tablename},:{columnname},{rownumber} = {expression}
	   e.g. mytable,:radvel,20 = 5 can be used to access a single table
	   element. This short form will not expand the table.

Examples:

           WRITE/TABLE mytable :RADVEL @20..30 13.5
           insert the value 13.5 in the column :RADVEL of table mytable.tbl
           for the 11 rows 20, 21, .. 30 .
