Finding range for each row

[pubhealthguy]

Hi,

I'm trying to analyze data by looking at changes in blood pressure (BP) over three measurements. I would like to add a column to each row that shows the difference between the highest and lowest of the three measurements.

For example: BP1- 120, BP2 - 160, BP3 - 140 -----> Range = (160 - 120) = 40

I am new to SAS and am at a loss of how to approach this. I have looked everywhere for a solution.

Any help would be great.

Thanks.

range = range(of BPZSY1 - BPZSY3);

You will find it useful to bookmark documentation.sas.com:
