Here's an example of how that would work. Some efficiency tricks: Use format dtdate9 on your datetime variable to summarize data by date. Use Range for the date variable to obtain the max time - min time. Datetime is stored as seconds, so convert to a number by dividing by 60 for minutes and another 60 for hours.Hi, Thank you for your message, this code was just an example.

Solved: Hi, Am just trying to concatenate first and last name in the following format: Doe, Jane Simple concatenate keeps giving me DoeJane. How do I.SAS does not write FIRST. and LAST. variables to the output data set, so you cannot display their values with the PRINT procedure. Therefore, the simplest method of displaying the values of FIRST. and LAST. variables is to assign their values to other variables. This example assigns the value of FIRST.TOURTYPE to a variable named FirstTour and ...Example 13.13. The following program tells SAS to process the sales data set by Store and Dept, so we can get a behind-the-scenes look at how we can find the first and last observations of two subgroups: LIBNAME stat481 'C:\yourdrivename\Stat481WC\01sasdata\sasndata'; PROC SORT data = stat481.sales …Hi 🙂.
