Hi Ed,



That sounds right to me. As you point out, map_attr.awk produces precisely one 
line of output for each line of input. So the command:



gawk -v f2=Emp_Attr.csv -f map_attr.awk ParentChild.csv>Map_Attr.csv



should produce a Map_Attr.csv file that has exactly the same number of records 
as the ParentChild.csv file. There must have been a cut & paste copy error.



Haritha -- can you please try again, taking care to make sure that the command 
is copied exactly as written above?



Regards,

Andy
