You would use the Outlook object model to do that. I have no idea about
Powerbuilder, but in VBA code if oMail is a mail item then this would attach
a file to the item:

Dim oAttach As Outlook.Attachment
Set oAttach = oMail.Attachments.Add("pathToTheFile")

Ken, No.. you did not understand my questtion al all... Let me explain you
again...

1. I am running an application using Powerbuilder.
2. From this application I am calling MS Outlook.
3. Users then search for a specific file (some .doc, .xls etc) to attach
with this Outlook.

I want to create something so that I can attach the file with Outlook
(instead user to look for it...since I know exactly what file needs to be
attached...)

all users are left to do is to put the Recipient address and Send....
