SAS - Help creating a date variable using arrays and do-loops

Hello.

Please take a look at the proc print screen grab. I'm posting because I have a homework assignment that's asking me to use arrays and do-loops to accomplish the following:

1) identify the date of the largest blood lead level, and
2) create a new variable for this date.

So, for example, since the first subject's highest blood lead level (sample 3 = 1.55) corresponds to 1/14/1990, the variable I want to create would identify 1/14/1990.

Similarly, since the third subject's highest blood lead level (sample 2 = 3.62) corresponds to 06/06/1990, the variable I want to create would identify 06/06/1990.

Does anyone know how I can write a program to do this?

Thanks,

GP
