-substr- should do what you need. So, assuming you always have 4 digits followed by two characters in variable str, try substr(str,1,4) for the digits and substr(str,-1,2) for the characters. See help strfun.

I am dealing with a string variable that has 4 figures and 2 letters,
something like this: 1234AB
As you can see there is no space, or comma, etc. divinding the figures
from the letters. 
What I wanna do is to create a new variable where I only keep the
figures and drop the letters. How can I do that? Does the command SPLIT
help me in this? 

Thank you very much.
