Subject: [Statisticians_group] Sorting in SAS by Numeric or Character VariablesHi,
I have a simple basic query. It is fact that if we convert a numeric variable to character variable it will save memory. Now let a SAS data set is look like below:
X1 X2 X3
01 AB 1
03 AC 31
02 SS 4
10 ww 15
It is clear that X1 and X2 are character variables where X3 is numeric.
Now my question is if I want to sort the data by X1 as a character variable and after converting it numeric variable which one take more times?
