st: reduce a variables numbers of digits to 4 counting from left

["Lassen, Peter, pla" <PLA@kl.dk>]

Hi,

I have a numeric variable of 9-12 digits, of wich only the first 4 digits counting from the left is of importance. I therefore have to get rid of the remaining 5-8 digits.
But how?

Best regards and thanks
Peter
