Thanks for your prompt answer. But I cannot see how these functions would help me with my problem. I try to explain it in another way: price_1 = 10; number = 1; result = ( value of price_number ) = 10 So all I need is a function that gives me the value of "price_number" where "price_" is a prefix and number is the value of another variable in the same observation.

hello, i have the following problem: For each observation in my dataset i have hundreds of columns. They are named: day_1 day_2 day_3 day_4 day_5..... Then I have a variable that contains a number, let's say n=4. Now I want to create another variable, let's say 'result', that is equal to day_n. In my example it should be: result = day_4 But n is not always 4. So I need a small programme that helps me to solve that problem. Thanks in advance for your help. matt
