Dear list

I know this is an old timer but i just dont get it.

I have a variable indicating birth date. The variable is in string format and looks like this

Mm/dd/yyyy

If the the month or day is single digit it looks like this
M/d/yyyy

I have removed the /'s by


gen newstrvar = subinstr(strvar, "/", "", .)

But form there i dont get it.

Ive used

Gen newdate = date (newstrvar, "MDY")

But that only gives me missing values.


What am i doing wrong and is there an easy way to do this?


lars
