Victoria wants to do the opposite:

My problem is similar to Maria's, but from your command I cannot figure out how to apply it to my case.

Basically I just need to keep the first 2 digits of my variable "code".


. g firsttwo = substr(string(var1),1,2)

. l

+-----------------+
| var1 firsttwo |
|-----------------|
1. | 11 11 |
2. | 222 22 |
3. | 3333 33 |
4. | 4444 44 |
+-----------------+
