" I don't even know what to input in order to use help."
The solution in these cases is always hidden in -help string functions-. A judicious application of the functions assembled there solves almost all of these problems:

Subject: st: Variable Creation
Dear Statalist:
I have a partial listing of the following variable, formatted as str9:
sitecode
--------
37087M022
37087M022
37173M035
37173M035
370810009
370810009
370810009
370810009
370810009
370810009
370810009
370870035
370870035
370870035
370870035
370870035
I would like to create an additional variable, site, as follows: site = xxx if sitecode = 37xxxyyyy. Site is the 3rd, 4th, and 5th characters of sitecode. I don't know how to do this, and what's more frustrating, I don't even know what to input in order to use help.
Sorry if this is too basic, but I do appreciate any help.
