parsing data in a function

I have a field ptage that contains the patients age formatted as XXXY
where XXX can be 1,2 or 3 digits and Y will be either D,M,Y

How can I parse out the XXX and the Y into separate fields?

           Num     Alpha  
21D =  21         D
3M       3           M
101Y   101       y

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

post sample values

This should help:

Dim strField As String
strField = "123D"
If (Len(strField) > 0) Then
    MsgBox Right(strField, 1)
    MsgBox Left(strField, (Len(strField) - 1))
End If
Your parsed fields wold be:

Alpha: Right([ptage],1)


Num:  Left([ptage],Len([ptage]) -1)

Have you read matthewspatrick's article on regular expressions? For the requirement you describe above, I would expect a pattern like:

With that, your number would be in group 1 and your letter code would be in group 2.
