Hi Andrew, Yes That's what I wanted. Thanks! Also, below is copied sequentially from CIW window : nth(0 a) (1.8115 1.013) nth(0 b) (1.8115 1.013) nth(0 a)==nth(0 b) nil Why the last 1 is getting returned nil, it should be t. I tried using car also but the last command is giving me nil output, i don't know why. Regards, Leo
