Starting from your saved data,
. infile str9 date float (gdp b c d e) using

(88 observations read)
. gen month = substr(date, 3, 2)
. gen year = substr(date, 6, 4)
. destring month year, replace
month has all characters numeric; replaced as byte
year has all characters numeric; replaced as int
. egen quarter = group(month)
. gen time = yq(year, quarter)
. tsset time
time variable: time, 40 to 127
. corrgram gdp, lags(25)
