I think that -todate- created by Nick Cox is a lot easier than Jospeh
Coveney's suggestion to Hans Baumgartner. Find it by -findit todate- and
install it. It goes like this (I let all dates be the fifteenth):
-------------------------------
clear
input str6 ymdate
200312
199802
end
gen ymddate=ymdate+"15"
todate ymddate , gen(bdate) pattern(yyyymmdd)
format bdate %d
list
-------------------------------
