I have a dataset with data by Congressional district:

. dataex congdist in 1/5


Code:
* Example generated by -dataex-. To install: ssc install dataex
clear
input str5 congdist
"AK-0"
"AL-1"
"AL-2"
"AL-3"
"AL-4"
end


I need to split the district state and district numbers (for merging with another data set) so that the hyphen is dropped and I get, e.g.,

AK 0
AL:1,

etc. Tried split, didn't work. Any help would be appreciated.

Thanks,

Ric
