For more see: -help string functions-

*------------------------- begin example --------------------------
drop _all
input str63 company
", Inc. (Exelon Corporation (NYSE:EXC))"
"Peppers & Rogers Group (TeleTech Holdings Inc. (NasdaqGS:TTEC))"

gen begin = strpos(company,":")+1
gen end = length(company) - 1
gen ticker = substr(company,begin,end-begin)

*-------------------------- end example ---------------------------
(For more on examples I sent to the Statalist see: )
