Converting alpha dates to date data type fields (m/d/yy)

I'm trying to convert a date field from an ascii file to an rpg date data
type.

The date coming in is an 8 byte alpha field in the format of mm/dd/yy BUT
when the month or the day is less than 10, it only serves one digit -

i.e. 09/05/02 shows up as 9/5/02.  I have no control over what this file
looks like when it arrives.

I tried converting it using the following code:

d $CDate          S               D   DATFMT(*ISO)

c     *mdy/         move      CBDATE        $CDate

but I get an error that '8/23/02 ' is an invalid date.

short of searching for slashes and manipulating this alpha field with
substrings to extract the date, is there an easy way to convert these?

thanks,

Rick
