Hi Xie Keshan,
Thanks for sharing your code - I'm new to SAS and still trying to get my head around how the code works but it does!
I was wondering what needs to be changed in the code for it to return the first variable (in this instance age1) if there are multiple modes instead of returning a random value?
Many thanks!
