Dear all,

I'm dealing with a large data set which one string var is completely
nested. I easily take off numbers from it, but I still breaking my
head trying to figure out how can I get from var words like "PP",
"Deputado Federal", "Senador", "Deputado Estadual". So, below a paste
few cases.

clear
inp str200 var1
"155 - VITAL DO REGO FILHO - PB - Senador"
"1111 -  - PP -  - Deputado Federal / 25888 - ATAIDES MENDES PEDROSA -
PB - Deputado Estadual"
"1111 -  - PP -  - Deputado Federal / 22333 - EDNALDO PEREIRA DE
SANTANA - PB - Deputado Estadual"
"151 - JOSE WILSON SANTIAGO - PB - Senador"
"45123 - ANTONIO HERVAZIO BEZERRA CAVALCANTI - PB - Deputado Estadual"
"1212 - DAMIÃO FELICIANO DA SILVA - PB - Deputado Federal"
end

gen var2 = regexs(0) if regexm(var1, "^[0-9a-zA-Z]*")
