How to count the number of observations in a SAS table?
I am very new to SAS. Now, I have a SAS data table as following:
Is there any way to save the number of observations in this table **using only PROC SORT and DATA step**? I want to hold the value in the log window, which is like "hold N=4" in the SAS log script.
Sorry for my unprofessional description. Thanks in advance.
