The first sentence shows a fundamental misconception.
A display format assigned to a variable has nothing to do with how
data are stored; it merely indicates how data are to be displayed.
That said, Ray's question underlines that -summarize- ignores display
format for daily dates.
Instead,
. codebook buydt
should do what Ray wants. Also, check out -summdate- (SSC).
