Is there a way to subtract one value of a variable (column) from another value of the same variable?
For instance, I have a single column of numeric values:
1
2
3
4
5
and I want to subtract the first value in the column from the second (i.e. 2-1), the second value from the third, etc.
Look in the online documentation for the DIF function.

Hi,
You can try something like this as suggested by data_null_
data have;
input num;
substract=dif(num);
datalines;
1
2
3
4
5
;
run;
Thanks,
