sir i have one small doubt:
if nm(1)=10 means it refers to col1 only right . sas have to look for value 10 in col1 only right.It means it search for value 10 in all rows that corresponds to col1 or only in row1 .if the loop executing for the first time means.I am not able to resolve what happening when i=1, i=2 etc .
